GEO 101 Lab: Metamorphic Rocks Exam
100% Accurate!!
rock cycle - ANSWERSa series of processes on the surface and inside Earth that slowly changes rocks
from one kind to another
migmatite - ANSWERSfoliated, ultra high-grade metamorphic rock with clear layers and large
grains/bands
gneiss - ANSWERSfoliated, high-grade metamorphic rock with visible mafic and felsic minerals
schist - ANSWERSfoliated, high-grade metamorphic rock that has visible micas and has medium to large,
flat, sheet-like grains in a preferred orientation
contact metamorphism - ANSWERStype of metamorphism that occurs when a magma chamber intrudes
the surrounding rock; the heat from the magma metamorphoses the surrounding rock
phyllite - ANSWERSa foliated intermediate-grade metamorphicrock, containing small crystals of mica and
chlorite that give it more or less glossy sheen
slate - ANSWERSfoliated, low-grade metamorphic rock that is dark gray in color and has microscopic
micas (fine grained)
shale - ANSWERSsedimentary rock that is protolith for slate
marble - ANSWERSnon-foliated rock that is effervescent and whose parent rock is limestone
