Detailed explanation-1: -Potassium aluminium silicates (KAlSi3O8), sodium aluminium silicates (NaAlSi3O8), and calcium aluminium silicates are the chemical names for feldspar (CaAl2Si2O8). The form of alkali metal or alkaline earth metal found in the molecule determines the chemical name of feldspar.
Detailed explanation-2: -The chemical formula of ‘Feldspar’ is KAlSi3O8. Feldspars are the most important rock forming minerals and constitute roughly two thirds of the igneous rocks.
Detailed explanation-3: -The chemical formula of ‘Feldspar’ is KAlSi3O8. Feldspars are the most important rock forming minerals and constitute roughly two thirds of the igneous rocks.
Detailed explanation-4: -Alkali feldspars rank with quartz and plagioclase as the most common minerals in the earth’s crust. Chemically they are represented by the formula (K, Na)AlSi3 O8.
Detailed explanation-5: -Common examples of alkali feldspars are microcline, orthoclase, and sanidine. Albite, oligoclase, and labradorite are some common examples of plagioclase feldspar.
