Webmica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic. Of the 28 known species of the mica group, only 6 are …
WebAltered biotite, produced through hydrothermal or weathering processes, produces vermiculite, a porous material that is used as an insulating material in gypsum wall board and in other heat insulating applications. When heated, vermiculite will expand to many times its initial volume, in an accordion-like expansion of its layered structure. WebShataputi abhrak bhasma and SPAB are considered to be finest form of biotite-calx (mica based) bhasma 14 and contains immunomodulatory properties. 18 SPAB has been shown to protect from heat-induced oligozoospermia and azoospermia, possibly by modulating p53 and Fas mediated apoptotic pathways and ameliorates germinal epithelial proliferation. …
WebMore often, magnetite is dispersed throughout a rock as microscopic crystals that form along the edges of iron-bearing minerals such as biotite, amphiboles and pyroxenes. In this dispersed form, it seldom constitutes enough of the rock’s volume to be detected by a hand held magnet, although the rock may exhibit a paleomagnetic signature that can be … WebPhyllite formation from slate that is further metamorphosed so that very fine grained mica mineral achives.

WebSchist has large, flattened grains of platy minerals like muscovite, biotite, and chlorite. These crystals are elongated and oriented roughly parallel to one another. Quartz and feldspar are often present and may or may not be elongated. Larger crystals of bulky minerals like garnet are commonly included. Schist.
