   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.

2. Etymology: Feld, field (from Middle High German veld, from Old High German feld) + Spath, spar

1. Feldspar

   Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.

1. feldspar

   Feldspar is a large group of rock-forming silicate minerals that make up over 50% of Earth's crust. They crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of metamorphic and sedimentary rocks. Feldspar is characterized by a specific crystalline structure and is typically rich in aluminum, potassium, sodium and calcium. The two most common types are Orthoclase (potassium feldspar) and Plagioclase (sodium and calcium feldspar). Feldspars are often used in the production of ceramics and glass.
