Biotite Mineral | Uses and Properties

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 …

Hornblende: Mineral information, data and localities.

An informal name for dark green to black amphiboles, mostly ferro-hornblende or magnesio-hornblende according to the current nomenclature. In the book "Rock-forming minerals, volume 2b, double chain silicates" by Deer, Howie & Zussman (1997), the term "hornblende" is used as a group name for all aluminous amphiboles in the calcium …

Kiglapait Mineralogy I: Apatite, Biotite, and Volatiles

The volatile chemistry of the Kiglapait intrusion is calculated from apatite and biotite chemistry. The intrusion contains an estimated 900 ppm P 2 O 5, 166 ppm F, and 12 ppm Cl. There is a maximum of 68 ppm H 2 O using calculated H 2 O from microprobe data, or a minimum of 8 ppm using H 2 O from infrared analysis.
