Question

Quizplus · Accepted Answer

Phyllite is a metamorphic rock that forms from the regional metamorphism of sedimentary rocks, commonly shales, at temperatures and pressures intermediate between those required for slate and schist. These conditions are typically found in the roots of ancient collisional mountain ranges, where two continental plates have collided and compressed sedimentary rocks. Therefore, phyllite would most likely be found at the eroding base of an ancient collisional mountain range.
