Classification of Minerals By Jessica Marcus

Chemical composition Native elements Gold, Silver, Sulfur Au, Ag, S Pyrite, Galena FeS, PbS Sulfides Hematite, Magnetite Fe2O3, Fe3O4 Oxides SiO2 KAl2(AlSi3O10)(OH,F,Cl)2 KAlSi3O8 Quartz, Mica, Feldspar Silicates

Silic- is for Silicon (s) Silicates Silic- is for Silicon (s) -ate is a suffix for “oxide “ Silicates are “oxides of silicon” Look at the reference table and calculate the weight of silicon and oxygen.

Silicates Mica Quartz Can you find the “silica” ? SiO2 KAl2(AlSi3O10)(OH,F,Cl)2 Can you find the “silica” ?

Silica Structure 4 oxygen atoms for every 1 silicon atom

Complexity Temp. Olivine Pyroxenes (Augite) Amphibole (Hornblende) Micas Feldspar, Quartz

How can 2 minerals with the same composition be so different? Graphite Diamond Chemical formula: C Chemical formula: C How can 2 minerals with the same composition be so different?

“Internal Arrangement of Atoms” controls most physical properties! What’s the point here? “Internal Arrangement of Atoms” controls most physical properties!

Review of Concepts: 1. Minerals can be identified by examining….. Physical Properties, including…. Luster, Hardness, Cleavage, Color, Streak, Density…. 2. Minerals are classified according to their….. Chemical Composition, including groups like…. Native Elements, Sulfides, Oxides, and the all important SILICATES 3. The “Basic Building Block” of the Silicate Minerals is…..

Review of Concepts: (continued) 4. The physical properties of minerals are generally controlled by….. Crystalline Structure…. …or the “orderly internal arrangement of the atoms”! What do graphite and diamond have in common?…… Identical Chemical Composition…. What accounts for the differences between graphite and diamond? ….the “orderly internal arrangement of the atoms!
