Minerals
The Study of minerals
Mineralogy
The appearance of a mineral in reflected light
Luster
the product of weathering
Sediment
degrees in condition(pressure & heat) that leads to metamorphic rocks
Metamorphism
hypothesis by Alfred Wegner that all continents move apart and are moving
Continental Drift
any naturally occurring inorganic solid that possesses an orderly crystalline structure
Mineral
The color of a mineral in powdered form
Streak
Detrital Sedimentary Rock that consists of round gravel size particals
Conglomerate
pressure from burial
Confining Pressure
Plate Boundaries where 2 plates move apart
Divergent Plate Boundaries
Any naturally occurring solid mass made of mineral-like matter
Rock
A mineral property that can vary and is often not diagnostic
Color
fine grained sedimentary rock composed of silt and clay
siltstone
Flat arrangement of mineral grains or structures
Ex.)Slate,Phyllite,Schist,Gneiss
Foliation
Plate Boundary where 2 plates move and collide together
Convergent Plate Boundary
a bond formed when two atoms share valence electrons
covalent bond
The common shape in which a crystal grows
Crystal Shape/Habit
sedimentary rock composed of clay minerals
shale
COntain equidimensional crystals and resembles a course grain igneuos rock
Ex.)Quartzite,Marble
Nonfoliation
Plate Boundary where 2 plates grind past eachother
Transform Plate Boundary
the density ratio of a mineral compared with an equal volume of water
Specific Gravity
The ability to resist scratching or abrasion
Hardness
Type of limestone made of sedimentary sea shells
Coquina
2 types of metamorphic agents
Heat and Pressure
The sinking of the crust because it is cold and dense
Slab Pull
