A. feldspar‘s and muscovite mica.B. calcite and dolomite.C. hematite and pyriteD. carbonates and iron sulfides tricky on
The answer is A. feldspar's and muscovite mica. Muscovite has a layered structure of aluminum silicate sheets weakly bonded together by layers of potassium ions. The following are some of the more common feldspar minerals: ?Albite, (Sodium aluminum silicate) ?Oligoclase, (Sodium calcium aluminum silicate) ?Andesine, (Sodium calcium aluminum silicate) ?Labradorite, (Calcium sodium aluminum silicate) ?Bytownite, (Calcium sodium aluminum silicate) ?Anorthite, (Calcium aluminum silicate) ?Microcline, (Potassium aluminum silicate) ?Sanidine, (Potassium sodium aluminum silicate) ?Orthoclase, (Potassium aluminum silicate)
