Mica Minerals are Major Rock Forming Minerals

When shale recrystallizes forming microscopic mica minerals between the sedimentary layers the rock turns into slate, a metamorphic rock. Muscovite mica. Muscovite mica is the most common mica found in gneiss, schist and granite. The name muscovite mica is derived from Muscovy-glass which used the mica in Russian window glass.

What is the difference between a rock and a mineral?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

Schist: Metamorphic Rock - Pictures, Definition More

What is Schist? Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity. This metamorphic environment is intense enough to ...

Mica Statistics and Information - USGS

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible. Layering in the divalent, or brittle, micas
