Allstract

One hundred thirteen Apollo 17 rake samples ranging in weight

from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy

ically and under the stereomicroscope while fitiLl in the storage cabinets

of the Lunar Receiving Laboratory Houston rexas The rocks are described

and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia

agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or

troctolite (1) microbrecci1~ (43) green gassy rock (probably melted

breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were

subdivided on the middotbasis of grain size into very fine (2) fine (21) fine

to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare

basslts Microbreccia subdivision was made on the basis of the degree of

coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy

matrix microbreccias (2) 30iL clods also vary in their consistency and

were grouped into friable soil clods (2) and soil clods transitional to

friable-matrix microbreccias (3) Classif~cation If individual rocks is

often difficult because (1) their study wafi limited to stereomicroscopy

(2) some are partially covered by fine dust vhich makes recognition of

textures and minerals difficult and (3) they grade from one type into the

other Therefore this classification will feave to be modified after

detailed microscopic electron microprobe and chemical study

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

the basis of grain si ze into very fine (2) fine (a) fire to medium (1)

medium (19) mediwn to coan3e (1) and coarse (16) lJare basalts This

classification will lle modified based on morE quantitative

mineralogic-petrologc-chemical parameters a laboratory studies of these

rocks progress Microbreccia subdlvision vTa made on the basis of the

degree of coherence of their matrices into coherent-matrix microbreccias

Allstract

One hundred thirteen Apollo 17 rake samples ranging in weight

from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy

ically and under the stereomicroscope while fitiLl in the storage cabinets

of the Lunar Receiving Laboratory Houston rexas The rocks are described

and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia

agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or

troctolite (1) microbrecci1~ (43) green gassy rock (probably melted

breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were

subdivided on the middotbasis of grain size into very fine (2) fine (21) fine

to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare

basslts Microbreccia subdivision was made on the basis of the degree of

coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy

matrix microbreccias (2) 30iL clods also vary in their consistency and

were grouped into friable soil clods (2) and soil clods transitional to

friable-matrix microbreccias (3) Classif~cation If individual rocks is

often difficult because (1) their study wafi limited to stereomicroscopy

(2) some are partially covered by fine dust vhich makes recognition of

textures and minerals difficult and (3) they grade from one type into the

other Therefore this classification will feave to be modified after

detailed microscopic electron microprobe and chemical study

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

vugs and vesicles some of which are sometimes lined by what appears to

be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have

long needles of what may be pyroxene The dominalt grain sizes of these

rocks range from 001-03 mm and that of ilmenite near vugs in 715870

may be as large as 05 mm Isolated olivine grails in 785790 reach

Coarse mare basalts are dark brownish gray to brownish gray to

medium dark gray to medirun gray to dark gcay to olive gray in appearance

and have varying amounts of vugs and vesicles sOYletime~ with crystals

(pyroxene) projecting into them These rocks are coherent to friable

and have dominant grain size ranging from 00 3middot-0il mm In 715970 some

olivine crystals reach longest dimensions of over 1 mm Major minerals

are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy

times olivine (01 5) One rock (715970) is noted for its high olivine

content of 025

Allstract

One hundred thirteen Apollo 17 rake samples ranging in weight

from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy

ically and under the stereomicroscope while fitiLl in the storage cabinets

of the Lunar Receiving Laboratory Houston rexas The rocks are described

and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia

agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or

troctolite (1) microbrecci1~ (43) green gassy rock (probably melted

breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were

subdivided on the middotbasis of grain size into very fine (2) fine (21) fine

to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare

basslts Microbreccia subdivision was made on the basis of the degree of

coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy

matrix microbreccias (2) 30iL clods also vary in their consistency and

were grouped into friable soil clods (2) and soil clods transitional to

friable-matrix microbreccias (3) Classif~cation If individual rocks is

often difficult because (1) their study wafi limited to stereomicroscopy

(2) some are partially covered by fine dust vhich makes recognition of

textures and minerals difficult and (3) they grade from one type into the

other Therefore this classification will feave to be modified after

detailed microscopic electron microprobe and chemical study

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

Allstract

One hundred thirteen Apollo 17 rake samples ranging in weight

from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy

ically and under the stereomicroscope while fitiLl in the storage cabinets

of the Lunar Receiving Laboratory Houston rexas The rocks are described

and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia

agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or

troctolite (1) microbrecci1~ (43) green gassy rock (probably melted

breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were

subdivided on the middotbasis of grain size into very fine (2) fine (21) fine

to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare

basslts Microbreccia subdivision was made on the basis of the degree of

coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy

matrix microbreccias (2) 30iL clods also vary in their consistency and

were grouped into friable soil clods (2) and soil clods transitional to

friable-matrix microbreccias (3) Classif~cation If individual rocks is

often difficult because (1) their study wafi limited to stereomicroscopy

(2) some are partially covered by fine dust vhich makes recognition of

textures and minerals difficult and (3) they grade from one type into the

other Therefore this classification will feave to be modified after

detailed microscopic electron microprobe and chemical study

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

Allstract

One hundred thirteen Apollo 17 rake samples ranging in weight

from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy

ically and under the stereomicroscope while fitiLl in the storage cabinets

of the Lunar Receiving Laboratory Houston rexas The rocks are described

and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia

agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or

troctolite (1) microbrecci1~ (43) green gassy rock (probably melted

breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were

subdivided on the middotbasis of grain size into very fine (2) fine (21) fine

to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare

basslts Microbreccia subdivision was made on the basis of the degree of

coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy

matrix microbreccias (2) 30iL clods also vary in their consistency and

were grouped into friable soil clods (2) and soil clods transitional to

friable-matrix microbreccias (3) Classif~cation If individual rocks is

often difficult because (1) their study wafi limited to stereomicroscopy

(2) some are partially covered by fine dust vhich makes recognition of

textures and minerals difficult and (3) they grade from one type into the

other Therefore this classification will feave to be modified after

detailed microscopic electron microprobe and chemical study

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

1 Introduction

In the present report descriptions and classifications of 113

Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy

pose of this study is to arrive at a preliminary classification of Apollo

17 rake samples based on macroscopic and stereOlLicroscopic examination

of the rocks while still in the storage cabinets of the Lunar Receiving

Laboratory Houston Texas mis preliminary classification has several

purposes First it aided us in selecting 54 representative samples from

the 113 total rake samples for our mineralogic IJetrologic bulk chemical

(via broad beam electron microprobe and neutron activation analysis)

mineral chemical (via focused beaJn electron microprobe analysis) and

trace element (via neutron activation analYilis) studies Second it may

serve as a petrologic basis for allocating ake samples to other Principal

Investigators for other studies such as age dating It is also hoped that

it may aid these investigators in interpreting their data before detailed

mineralogic and petrologic data are available

The classification proposed here Ls necessarily preliminary

The difficulties encountered in establishing the present preliminary

classification reEmlts from a number of lLmitations First examination

was restricted to stereomicroscopy of the samples while stiLL in the

storage cabinets in Houston Second some of the samples are partially

Neutron activation analysis will be carried out on the same sample for

which we will prepare electron microprobe sections in collaboration with

G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

3 Classification

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

the basis of grain si ze into very fine (2) fine (a) fire to medium (1)

medium (19) mediwn to coan3e (1) and coarse (16) lJare basalts This

classification will lle modified based on morE quantitative

mineralogic-petrologc-chemical parameters a laboratory studies of these

rocks progress Microbreccia subdlvision vTa made on the basis of the

degree of coherence of their matrices into coherent-matrix microbreccias

(41) and friab1e-matrix microbreccias (2) [oL clods also vary in their

consistency and were grouped into friable Bo l clods (2) and soil clods

Mediwn mare basalts are medhun dark gray to medium gray to

dark gray or dark brovnlish gray in color and exhibit varying allounts of

vugs and vesicles some of which are sometimes lined by what appears to

be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have

long needles of what may be pyroxene The dominalt grain sizes of these

rocks range from 001-03 mm and that of ilmenite near vugs in 715870

may be as large as 05 mm Isolated olivine grails in 785790 reach

sizes up to 007 rmn in longest dimensjon Major minerals are

5

plagioclase (020-30) pyroxene (055-60) ilmenite (010-20) and someshy

times a mafic mineral possibly olivine (2-5)

Coarse mare basalts are dark brownish gray to brownish gray to

medium dark gray to medirun gray to dark gcay to olive gray in appearance

and have varying amounts of vugs and vesicles sOYletime~ with crystals

(pyroxene) projecting into them These rocks are coherent to friable

and have dominant grain size ranging from 00 3middot-0il mm In 715970 some

olivine crystals reach longest dimensions of over 1 mm Major minerals

are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy

ACKNOWLEDGMENT

We wish to express our sincere appreciation to the members of

the Lunar Sample Curators Office Johnson 3pacecraft Center Houston

Texas and their contractors who have been most helpful during the

examination of the Apollo 17 rake samples We are particularly grateful

for the many excellent photographs of the BampleE and the assiBtance in

typing and editing thiB report Without their diligence this study would

not have been possible

covered by fine dust which makes identification of textures and minerals

difficult particularly in view of the fact that the samples could not be

altered in any way (eg broken) Third rocks sometimes grade from one

type into the other Hence the preliminary clas ification proposed here

Ifill have to be mocLt fied as more detailed mineralogic petrologic and

compositional daGa l)ecome available

2 Sample 10ca1ities

The samples described here are from fow localities at the

Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering

sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)

and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy

tion lA all are mare basalts AIl but one of the 12 station 2 samples

are coherent-matrix microbreccias the exception is a cataclastic anorshy

thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy

tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods

1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate

(see section 4 Nwnerical sample inventory and sample index)

3 Classification

31 General characterization

Tbe 113 rake samples were classified on the basis of macroscopic

and stereomicroscopic examination while still in the storage cabiLets at

the Lunar Receiving Laboratory Houston Texas On the basis of texture

and mineral content the Apollo 17 rake srunples were classified iLto

classification will lle modified based on morE quantitative

mineralogic-petrologc-chemical parameters a laboratory studies of these

rocks progress Microbreccia subdlvision vTa made on the basis of the

degree of coherence of their matrices into coherent-matrix microbreccias

Fine mare basalts are grayish black to dark gray in color and

show varying amolwt s of vugs and vesi cles Sometlmes vesi cles appear

to be lined by pJates of ilmenite (715460 715690) Dominant grain

size is less thaI 01 mm Major minerals are plagioclase (25-30)

pyroxene (060) aYJd ilmenite (010) and sometimes mafi c silicates

Mediwn mare basalts are medhun dark gray to medium gray to

dark gray or dark brovnlish gray in color and exhibit varying allounts of

vugs and vesicles some of which are sometimes lined by what appears to

be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have

long needles of what may be pyroxene The dominalt grain sizes of these

rocks range from 001-03 mm and that of ilmenite near vugs in 715870

may be as large as 05 mm Isolated olivine grails in 785790 reach

sizes up to 007 rmn in longest dimensjon Major minerals are

Coarse mare basalts are dark brownish gray to brownish gray to

medium dark gray to medirun gray to dark gcay to olive gray in appearance

and have varying amounts of vugs and vesicles sOYletime~ with crystals

(pyroxene) projecting into them These rocks are coherent to friable

and have dominant grain size ranging from 00 3middot-0il mm In 715970 some

olivine crystals reach longest dimensions of over 1 mm Major minerals

are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy
