Feldspar vs Mica
As nouns the difference between feldspar and mica is that feldspar is any of a large group of rock-forming minerals that, together, make up about 60% of the earth's outer crust. The feldspars are all aluminum silicates of the alkali metals sodium, potassium, calcium and barium. Feldspars are the principal constituents of igneous and plutonic rocks while mica …

Feldspar Group Feldspars are the most abundant minerals in the crust. The compositions of most feldspars can be represented by the ternary system anorthite (CaAl2Si2O8)—albite (NaAlSi3O8)—orthoclase (KAlSi3O8). Certain compositions within this system can only be attained at elevated temperatures, and consequently
