Which rock consists of quartz feldspar and mica?

Quartz, feldspar and mica are some of the most abundant minerals in the earth's crust. Quartz (SiO2) is present in almost all rocks. It is hard, resistant to chemical weathering and has no cleavage, which means it is also resistant to physical weathering.

In gneiss, the minerals may have separated into bands of different colours. In the example shown in Figure 7.2.4d, the dark bands are largely amphibole while the light-coloured bands are feldspar and quartz. Most gneiss has little or no mica because it forms at temperatures higher than those under which micas are stable.

Muscovite and K-feldspar (adularia) were dry-ground to — 200/inch particles, which were suspended in water. These suspensions were “titrated” with KCl, and the pH was recorded as a function of KCl concentration and temperature. The results indicate that muscovite and adularia react with water to produce a surface film in which H+ has displaced K+. The “titration” curves show some ...
