Feldspars may be partly weathered or altered to clay minerals, sericite (fine-grained muscovite mica), saussurite (mixture of albite, epidote and others – disintegration product of calcic plagioclase) which gives them somewhat dirty and worn-out appearance. Plagioclase is more susceptible to weathering than K-feldspar and Ca-rich anorthite is the least resistant. This is one of the reasons ...
Alkali feldspar has the formula KAlSi 3 O 8, potassium aluminosilicate. The formula actually is a blend ranging from all sodium (albite) to all potassium (microcline), but albite is also one endpoint in the plagioclase series so we classify it there.
Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various applications are typically mined from granitic pegmatites.
