gneiss

coarse grained, light dark banding foliation

high grade reigonal metamorphism

granite or shale

schist

med-coarse grained

med grade reigonal metamorpism

shale or phyllite

phyllite

med to fine grained, glossy, wavy foliation

intermed reigonal meramorphism through schist and slate

shale

slate

fine grained, often blue-gray, rock cleaves on flat surfaces

low grade reigonal metamorphism

shale

quartzite

coarse grained, no foliation, has chipping

med to high grade reigonal metamorphism

sandstone

marble

coarse grained

reigonal or contact metamorphism

limestone or dolostone

granite vs metamorphic gneiss

granite can be the parent of gneiss when granite undergoes heat and pressure it results in gneiss.
