Feldspar
Feldspar - Mineralogy, Identification, Uses: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, …

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 …

The mineralogy of sandstones: feldspar grains
Feldspars are also common in metamorphic rocks. As such, feldspar is an important (usually subordinate) component of most terrigenous clastics, reflected in its inclusion in QFL classification schemes. The two major groups of feldspar are potassium feldspars and plagioclases. All have low relief in plain polarized light (similar to quartz).

Alkali Feldspar
Alkali feldspars constitute a solid-solution between K-feldspar or orthoclase molecule (Or) and albite (Ab), which represents also the sodic end-member of the plagioclase series. Anorthite (Ca[Al 2 Si 2 O 8]; An) is present in small quantities in alkali feldspars, usually constituting less than 5% of the solid solution and predominantly found in Na-rich alkali …

5.2 Chemical Weathering – Physical Geology
The hydrolysis of feldspar can be written like this: CaAl 2 Si 2 O 8 + H 2 CO 3 + ½O 2 —-> Al 2 Si 2 O 5 (OH) 4 + Ca 2+ + CO 3 2-plagioclase + carbonic acid —-> kaolinite + dissolved calcium + carbonate ions. This reaction shows calcium plagioclase feldspar, but similar reactions could also be written for sodium or potassium feldspars.
