Minerals

There are 1000’s of minerals out there but only a few dozen common ones.

How are minerals different from rocks?

Atoms form minerals

Minerals form rocks

Organized Internal Arrangement Of atomsIAOA

Crystals StructureTetrahedron


Minerals from solution

Precipitation from solution


Evaporation from solution


Cooling of magma

How are Minerals identified?

physical properties: color, hardness, cleavage, fracture, streak, and luster

chemical properties: reaction to acid

Color not a good identifier.

Some minerals have different colors

Different minerals can have the same color


Luster how the mineral reflects light.– Metallic – Nonmetallic


streak color of a mineral in its powdered form


Hardness is based on the internal arrangement of atoms

Strong bonds mean hard minerals

Diamond = 10

Talc = 1


Cleavage flat, smooth, shiny, surfaces occur along weak atomic bonds

How it breaks (in shapes)


fracture uneven, rough surfaces

Breaks randomly


Reaction to acid chemical reaction to acid confirms calcite

Feel Soapy, greasy, etc.

Magnetismmagnetic properties

Reacts to Ultraviolet light

Some minerals that glow?

Let’s make some minerals

We will melt down some bismuth into lava.

Then I will cool it down slowly.Last I will drain away any extra lava
