Rocks

Field Assignment Part: I By: Alexis Burton

ROCKS

• Sedimentary rocks consist of three-quarters of the rocks at the Earth’s surface. Sedimentary rocks form at the surface in environments consisting of beaches, rivers, the oceans, and everywhere else where there is sand, mud, and different types of sediment collect.

They come in all different shapes & sizes!

SEDIMENTARY ROCKS

METAMORPHIC ROCK

Is a non-foliated metamorphic rock that forms concluded recrystallization below environments of high viscosity and

directed pressure. Self-possessed predominantly of amphibole and plagioclase, frequently with very little quartz.

ABOUT METAMORPHIC ROCK/AMPHIBOLITE

SCHIST/METAMORPHIC ROCK

This metamorphic rock that contains well industrialized foliation. That frequently comprises significant amounts of

mica which permit the rock to split into thin pieces.

ABOUT SCHIST

QUARTZITE/METAMORPHIC

I think I would recall this being an Antietam quartzite. – consists of a white to gray like-to medium-grain quartzite. The formation consists of a formation that makes up

one of three different components that go along with the Chilhowee group, which part of the lower layers of blue ridged Mountains.

ABOUT QUARTZITE

SEDIMENTARY/RIVER ROCK

I think these rocks are both Metamorphic rocks or igneous rocks because that have been malformed by great heat or pressure. And have a quarter like size to them.
