Potassium feldspar or "K-feldspar" varies in crystal structure depending on its crystallization temperature Microcline is the stable form of potassium feldspar below about 400° C Orthoclase and sanidine are stable above 500° C and 900° C, respectively, but they endure as long as they need to at the surface as metastable speciesUniversity of Minnesota’s Mineral Pages: Potassium Feldspar,Within the potassium feldspar group, the occurrence of each potassium feldspar member varies slightly Orthoclase is the most common potassium feldspar, forming the majority of potassium feldspar found in felsic plutonic igneous rocks, some high temperature veins, and higher-grade metamorphic rocksTHE FELDSPAR GROUP - Amethyst Galleries Mineral Gallery,The feldspar group is a fairly large group with nearly 20 members recognized, but only nine are well known and common Those few, however, make up the greatest percentage of minerals found in the Earth's crust The following are some of the more common feldspar minerals:

Feldspar - Wikipedia

Albite is considered both a plagioclase and alkali feldspar Alkali feldspars Alkali feldspars are grouped into two types, those containing potassium in combination with sodium, aluminum, or silicon, and those where potassium is replaced by barium The first of these include:Feldspar Distinctions, Characteristics & Identification,The high potassium content and high strength of K-feldspar make it the best mineral for potassium-argon dating Alkali feldspar is a crucial ingredient in glass and pottery glazes Microcline has a minor use as an abrasive mineral images of feldspar - montmathscoza,Feldspar: Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium Feldspars make up more than half of Earth's crust, and professional literature about them constitutes a large percentage of the literature of mineralogy Learn more about the properties and uses of feldspar in this article
