15 Cards in this Set

  • Front
  • Back
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
