Jun 01, 2013 · The Spruce Pine Mining District had more than 700 mica and feldspar mines, according to the N.C. Geological Survey. There may be two or three times as many prospective pits in the district, the survey contends. The mica mines went full bore until solid-state electronics were developed in the 1960s, causing many to close. ×

Mica Minerals are Major Rock Forming Minerals

Mica Minerals are Major Rock Forming Minerals

Mica Minerals are Major Rock Forming Minerals. Mica minerals are major rock forming minerals found in gneiss, schist and granite. The mica group includes muscovite mica and biotite mica. They usually form in layers of sediment on ocean floors. Weathering of continental rocks breaks large and small chunks of rock off the larger older rocks.

Muscovite, KAl 2 Si 3 AlO 10 (OH,F) 2, is a high-aluminum mica common in felsic rocks and in metamorphic rocks of the pelitic series, derived from clay. Muscovite was once commonly used for windows, and the productive Russian mica mines gave muscovite its name (it was once widely known as "Muscovy glass").

A variety of Muscovite Greenish, Cr-bearing variety of muscovite (trivalent Cr replaces Al in the crystal structure). Note that trivalent V can also cause a greenish colour in muscovite (cf. vanadian muscovite, roscoelite). Compare mariposite, a Cr-bearing phengite.
