The name "biotite" is used in the field and in entry-level geology courses because these minerals generally cannot be distinguished without optical, chemical, or x-ray analysis.. Biotite is a rock-forming mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.It also forms under metamorphic …

EDS analysis shows that graphite tailing contains 5%-13% SiO 2 and 4%-8% Al 2 O 3. Mica mineral in graphite tailing has color similar to that of pure sericite but different from that of pure biotite, indicated by Optical Microscope. It is concluded that the mica mineral in graphite tailing is sericite of muscovite subtype.

Ti in biotite (Table 4) increased with temperature at constant 661 JOURNAL OF PETROLOGY VOLUME 41 pressure and decreased with pressure at constant temperature, as has been shown by Patiño-Douce (1993). The breakdown of biotite in runs containing 4 wt % added H2O occurred between 850 and 900°C at 10 kbar, and at >800°C at 15 and …

As estimated from the study of thin sections using the visual comparison technique of Terry and Chilingar (1955), biotite accounted for only ~ 0–5% of the pink bands but ~ 20% of a representative specimen of a prominent black band (Table 1). Biotite appeared to be the only mafic mineral in the rock: No amphiboles or pyroxenes were …
