Naturally-occurring elements and compounds are called minerals.
Naturally occurring mixtures of minerals, large deposits of single minerals, or organic materials are called rocks.
Crystalline or amorphous
Luster (metallic or nonmetallic)
Hardness (1-10 Moh’s scale)
Streak (color of powdered mineral)
Special – magnetic, reacts with acid, ore
HELP…THIS IS BORINGGGGGGGGG !!
STILL BORING !!!!!!!!!!
Types: Igneous, metamorphic, sedimentary
Varying chemistry (minerals: natural compounds)
Varying ages (relative and absolute age-dating)
Sedimentary: when deposited
Igneous: age starts when freezes
Metamorphic: when altered by heat/pressure
Dolomite (( Ca, Mg) CO3)
Igneous, metamorphic, or sedimentary
Rock Texture: FoliatedThin Sections:
Sandstone (SiO2 -quartz)
Shale (quartz + clay minerals)
Igneous or sometimes Sedimentary
Sedimentary or Metamorphic
