3.6.2 Feldspars. Feldspars are especially common minerals and make up about 60% of the Earth's crust. They crystallise from a wide spectrum of magmas and are found in many metamorphic and sedimentary rocks. The name 'feldspar' refers to a group of silicate minerals that share the same basic structure. The three most important feldspar minerals are orthoclase (KAlSi 3 O 8), albite (NaAlSi 3 O …

Feldspar Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldsparrich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Feldspars | Encyclopedia.com

perthite A series of layers that occurs as intergrowths in alkali feldspars which form at high temperatures and cool slowly, unmixing as they cool. Most alkali feldspars in such slowly cooled rocks (e.g. plutonic and igneous) consist of an alkali feldspar host with an exsolved, sodium-rich, plagioclase feldspar phase that segregated from the alkali feldspar during cooling.
