Physical Properties. Biotite Mica: Biotite usually looks dark and can vary in transparency, from opaque to somewhat see-through. It’s a bit harder than Muscovite, scoring higher on the Mohs scale, which measures mineral hardness. Muscovite Mica: Muscovite tends to be lighter in color and more transparent than Biotite.

Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock. Generally, the slower the molten rock cooled, the larger it’s mineral crystals with K-Feldspar megacrysts forming in special circumstances greater than 5cm. During formation of granite it is buried below kilometers of rock and sediment

Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color which is very friable and has very low weathering resistance. It crystallizes with a monoclinic geometry. Its name is derived from the Greek glaucos (γλαυκός) meaning 'bluish green', referring to the common blue-green color of the mineral; its sheen (mica glimmer)

Vermiculite is found in fine, rare, and somewhat larger sheets, and in other clay minerals with particles <4 μm. It is formed by weathering or hydrothermal alteration of biotite or phlogopite. Vermiculite is an essential ingredient of soil and clay sediments. The mineral can be transformed, easily and quickly, into smectite in surface weathering.
