is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. These micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

Biotite is used extensively to constrain ages of rocks, by either potassium-argon dating or argon–argon dating.

it is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg,Fe)3AlSi3O10(F,OH)2.

it is a unifying open source computational biology framework.

it symbolizes self-reflection, protection, and adaptability. The crystal is attuned to the air element, evoking mental clarity and emotional balance. Biotite is also a planetary star stone for Mercury, the planet of communication and intellect. Link

it has a common theme of being a foundational element to the whole and for forming organization in an environment of chaos. We hope to embody those principles.
