geology lab quiz metamorphic rocks
100% Accurate!!
metamorphic rocks - ANSWERSrocks changed from one form to another by intense heat, intense
pressure, or the action of watery hot fluids
parent rock - ANSWERSthe rock type that was metamorphosed. parent rocks can be any of the three
main rock types: igneous rocks, sedimentary rock, or even metamorphic rock
sedimentary conglomerate, sandstone, and limestone - ANSWERSmetaconglomerate, quartzite, and
marble
shale - ANSWERSslate, phyllite, schist, and gneiss
hornfels - ANSWERSformed only in a narrow zone of contact metamorphism next to the intrusion of
magma
contact metamorphism - ANSWERSoccurs locally, adjacent to igneous intrusions and along fractures that
are in contact with watery hot fluids
hydrothermal metamorphism - ANSWERSinvolves condensation of gases to form liquids, which may
precipitate mineral crystals along the fractures
regional metamorphism - ANSWERSoccurs over very large areas such as deep within the cores of rising
mountain ranges and generally is accompanied by folding rock layers. is caused by large igneous
intrusions that form and cool over long periods
mineralogical composition - ANSWERSis a description of the kinds and relative abundances of mineral
crystals that make up the rock.
