Biotite - Clark Science Center

Biotite is common in a variety of igneous and metamorphic rocks. In igneous rocks, it is found more commonly in silicic and alkalic rocks, e.g. granties, diorites, gabbros and peridotites. It is important in metamorphic rocks including schists, gneisses, phyllites, and hornfels. Also found in immature sedimentary rocks, but will alter to clay ...
