What is a roof pendant?
a cap of metamorphic rocks over an igneous pluton
What three minerals, all of the same chemical composition, form polymorphs depending on the pressure and temperatures at which they are stable?
andalusite, kyanite, and sillimanite
Amphibolite is a foliated metamorphic rock composed principally of hornblende and plagioclase feldspar. How might it form?
by regional metamorphism of volcanic rocks such as andesite and basalt.
