• Mineral : single substance(an
element or a compound) to form
rocks
1)mineral of an element – Ag, Cu,
Fe, Diamond
2)mineral of a compound – most
of minerals, CaMg(CO3)2
(dolomite), CaCO3(Calcite)
• Five characteristics of minerals
1)solids
2)form naturally
3)never be a part of living things
4)definite chemical composition ex)
CaSO4(gypsum)
5)the atom of minerals are connected to
one another in an orderly, repetitive
arrangement – crystal
• Groups of minerals
1)silicates(( )SiO) – most rock forming
mineral
2)oxides – AlO, FeO
3)sulfides – CuS, ZnS
4)halides – NaCl(halite), AgI, ( )Br, Na2F
5)carbonates – CaCO3(calcite),
CaMg(CO3)2(dolomite)
6)sulfates – CaSO4(gypsum)
• Minerals of silicates(( )SiO)
1)Ferromagnesian – significant
amount of iron and magnesium, dark
in color, bigger density
2) Nonferromagnesian
feldspar – most abundant mineral,
pink, white or gray
quartz – common and various uses
for industry
