WebNo, biotite is a mica. The mica group is another mineral group, different from the feldspar group. Micas are isosilicates - the atomic structures of the mica group form strong bonds in one direction (‘horizontally’), but weak bonds in the other direction (‘vertically’) - micas form flat sheets which split into flakes. WebCan refer to a volcanic rock with higher silica composition, or the minerals that make up those rocks, namely quartz, feldspar (both potassium feldspar and plagioclase feldspar), and muscovite mica. Felsic rocks are lighter in color and contain more minerals that are light in color, but can contain some biotite and amphibole.
