|
Slate
|
metamorphic, foliated, very fine grained, excellent rock cleavage, low-grade metamorphism of shale
|
|
|
Phyllite
|
metamorphic, foliated, composed of fine crystals of muscovite, minerals not large enough to be seen, glossy sheen, wavy surfaces
|
|
|
Schist
|
metamorphic, foliated, medium to coarse grained, platy minerals (micas) predominate
|
|
|
Gneiss
|
metamorphic, foliated, medium to coarse grained, banded appearance, alternating layers of feldspar-rich layers and bands of dark ferromagnesian minerals
|
|
|
Marble
|
metamorphic, non-foliated, coarse grained, protolith was limestone, composed essentially of calcite or dolomite crystals, reacts with HCL acid
|
|
|
Quartzite
|
metamorphic, non-foliated, formed from a parent rock of quartz-rich sandstone, quartz grains are fused together making it a hard dense rock
|
|
|
Conglomerate
|
sedimentary, derital/clastic, individual particles are rounded
|
|
|
Shale
|
sedimentary, derital/clastic, individual particles too small to see, bedding planes clearly visible in rock
|
|
|
Sandstone
|
sedimentary, derital/clastic, minerals typically include quartz and feldspar so this rock scratches glass
|
|
|
Limestone
|
sedimentary, chemical, many varieties, clastic or non-clastic, biochemical or inorganic, fossils common, softer than glass
|
|
|
Coal
|
sedimentary, non-clastic, biochemical, low density, black
|
|
|
Chert
|
sedimentary, non-clastic, biochemical, very fine grained, harder than glass
|
|
|
Rock Salt
|
sedimentary, non-clastic, inorganic, NaCl
|
|
|
Transgression Sequence
|
indicates sea level rise, fine grain sediment over coarse grain sediment
|
|
|
Regression Sequence
|
indicated sea level fall, coarse grain sediment over fine grain sediment
|
