Properties of Minerals | Earth Science | Visionlearning

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level.

Biotite is a common rock forming mineral, being present in at least some percentage in most igneous and both regional and contact metamorphic rocks. The typical black to brown color of biotite is characteristic although it is difficult to distinguish brown biotite from dark brown phlogopite.

Biotite – A Common Rock Forming Mineral

Biotite is a member of the mica branch of the silicate mineral group. It is common as a rock-forming mineral and is found associated with muscovite, feldspar, and quartz. It has a widespread occurance and is present in all three rock types igneous, metamorphic, and sedimentary. It is classified as a Phyllosilicate.

The splendent luster and dark sheets of this mineral from the mica group distinguish it from the others in the group. It is one of the rock-forming minerals and is widely distributed in igneous rocks. Vermiculite, which forms as an alteration of biotite, has water molecules interlayered in the sheets.

Biotite Wikipedia

Biotite is a sheet silicate. Iron, magnesium, aluminium, silicon, oxygen, and hydrogen form sheets that are weakly bound together by potassium ions. It is sometimes called "iron mica" because it is more iron-rich than phlogopite.

University of Minnesota's Mineral Pages: Biotite

A common, widespread, rock-forming mineral, biotite is a significant mineral in granites, diorites, and igneous pegmatites. In pegmatites, biotite crystals can be very large. It also occurs in schists, gneisses, and hornfels that resulted from either regional or contact metamorphism.
