Chlorite: WebAbstract: Biotite + plagioclase + quartz (BPQ) is a common assemblage in gneisses, metasediments and metamorphosed granitic to granodioritic intrusions. Melting experiments on an assemblage consisting of 24 vol. % quartz, 25 vol. % biotite (XMg = 0·38–0·40), 42 vol. % plagioclase (An 26–29), 9 vol. % alkali feldspar and minor apatite, titanite and …
WebBiotite. Biotite–K (Mg,Fe)3AlSi3O10 (OH)2–is a dark, iron-rich mica that has a monoclinic crystal system. The octahedral layer is entirely occupied by Mg2+ and Fe2+ and the mineral is therefore trioctahedral, since all octahedra are occupied. The source of the lattice charge is the presence of Al3+ in place of Si4+ in 1/4 of the tetrahedral ... WebResources Lockyer's All the Women of the Bible Chapter 2.
