Minerals - Advanced

 

 

       This page is dedicated to the more interesting thing about minerals as well as a greater understanding of them. Minerals are mostly known for their prettiness from the forms that they can develop but there those same minerals found in your everyday life that you don't notice.

Mineralogy Help

 

     When I was in mineralogy (in the year 2000), learning over 100 minerals as well as their chemical formulas and properties was probably the hardest thing in geology I have ever done. So I made a study sheet that hopefully could help some of you. Just click on the box to download it.

 

Minerology


Chemical Formula

 

Example #1 - HCl - Halite (AKA salt)

H - Cation

Cl - Anion

 - Grouped as Chloride (due to the Chlorine anion)

Example #2 - KAlSi3O8 - Orthoclase

KAl - Cation

Si3O8 - Anion

 - A silicate due to Si and O group


Mineral Structure

Graphite (both have C as their chemical formula) Diamond

Graphite Lattice                            Diamone Lattice

Since graphite is formed into sheets, it falls apart much more easily than diamond which is formed into an impenetrable lattice

                 Halite                                               Halite Structure

Halite         Halite Lattice

The square shape of the structure causes the mineral to break off in tiny cubes (a perfect example of cleavage in 3 directions @ 90°)
