Biotite and quartz

Webschist, megascopically crystalline rock that has a highly developed schistosity, or tendency to split into layers. Banding (foliation) is typically poorly developed or absent. Most schists are composed largely of platy minerals such as muscovite, chlorite, talc, sericite, biotite, and graphite; feldspar and quartz are much less abundant in schist than in gneiss. Web— Biotite is abundant in Newingham Tonalite such as exposed in road cuts in the NW Sec. 5 T36N R20E and NW NW Sec.2 T36N R19E and a railroad cut in NW NW Sec. 27 T37N R20E (Sims et al., 1992). — Biotite is common in the Marinette Quartz Diorite exposed widely south of Niagara. Associated minerals are prochlorite, hornblende and plagioclase.
