Biotite is a form of mica, and can be seen without difficulty in the right kind of rocks.
A biotite is a variety of dark brown mica, a mixed aluinosilicate and fluoride of potassium, magnesium and iron.
Not much usually around 100-120.
Biotite gneiss could have a number of protoliths (parent rocks), and those protoliths could be igneous or sedimentary; the sedimentary parent rock could be a fine-grained shale, high in biotite composition, or a granitic rock, high in biotite.
