MINERAL FAMILIES and RESOURCES
• Classified into 7 groups
• Based upon their chemical composition

I Native Elements:
• consist of a single element
Examples:
Silver (Ag)
Copper (Cu)
Graphite (C)
Sulfur (S)

IV Halides
- made of a combination of metals and the nonmetallic elements known as halogens.
Examples:
Halite (NaCl)
Fluorite (CaF2)

V Carbonates : -
- compounds of metals with carbon and oxygen.
Examples:
Calcite (CaCO3)
Dolomite CaMg(CO3)2

- compounds of various elements with silicon (Si) and oxygen (O).
- the most abundant group-make up 90% of Earth’s Crust-these elements form a unit called a tetrahedron
Examples: Quartz, clay, talc, mica, olivine
VII Silicates: Largest group

Structural Formula
Draw out:
– the arrangement of these atoms determines the crystal shape that resultsThe silica tetrahedron is the basic building block of minerals
