How is biotite made
WebBiotite, also known, as ‘black mica’ is a rock-forming femic phyllosilicate that occurs in several igneous and metamorphic rocks. The mineral was named in honor of the French scientist Jean-Baptiste Biot, who devoted his life to study the optical properties of the micas.

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. 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 …
WebIn the biotite zone (~ 300–400 °C), biotite nucleates and grows as widely spaced, dark-colored porphyroblasts that give such schists a “spotted” appearance in hand specimen. This occurs via the same reaction noted previously for initial biotite porphyroblast growth in contact metamorphic aureoles.
