2021-11-24 Feldspar is the name of a group of rock-forming minerals that make up as much as 60% of the Earth’s crust. Feldspar forms crystals from magma in both intrusive and extrusive rocks, and they can also happen as compact minerals, as veins, and are also present in many types of metamorphic rock.

Rock formed entirely of plagioclase feldspar is known as anorthosite. What is quartz made of? ' Quartz is an igneous rock that is composed of oxygen and silicon atoms in a continuous makeup of silicon-oxygen tetrahedra (SiO4). Each individual oxygen atom is shared between two tetrahedra atoms, giving quartz the final chemical formula ...

feldspar - 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 feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Alkali feldspar is made up of solid solutions of K-feldspar and albite. Plagioclase, or a plagioclase feldspar, is a solid solution formed by the reaction of albite and anorthite. Only a small solid solution exists between K-feldspar and anorthite, and immiscibility occurs in the two other solid solutions at temperatures found in the Earth's crust.
