In rocks they are usually flakes or layers of flakes. Margarite is a calcium rich member of the mica group of the phyllosilicates with formula: Ca Al 2 (Al 2 Si 2)O 10 (OH) 2.It forms white to pinkish or yellowish gray masses or thin laminae. Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. It is a very common material, and is the oldest known ceramic.Prehistoric humans discovered the useful properties of clay and used it for making pottery.

Perhaps up to one fifth of the crust is composed of gneissic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. Sheet mica prices vary with grade and can range from less than $1 per kilogram for low-quality mica to more than $2,000 per kilogram for the highest quality. Sheet mica is recovered by either sinking a shaft along the strike and dip of a pegmatite or by open-pit surface mining of semi-hard pegmatite ore.

Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. It crystallizes in the monoclinic crystal system.It typically has a specific gravity of around 3 and a Mohs hardness of 4. Sheet mica is obtained from coarse textured igneous rocks like pegmatite along with large crystals of feldspar and quartz. The mica minerals like Muscovite, phlogopite and Biotite make some rocks to sparkle as they break very easily into thin parallel sheets of flat surfaces , which reflect the light. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. In India and Eastern Europe, muscovite can be found in crystals large-enough to be split into sheets to be used as windowpanes. The construction of paper capacitor is between the two tin foil sheet and they are separated from the paper, or, oiled paper & thin waxed. The Muscovite mica is better in the electrical properties and the other Mica has a high-temperature resistance. Perhaps up to one fifth of the crust is composed of gneissic rocks.
