ORTHOCLASE (Potasium Aluminum Silicate)

Orthoclase is a polymorph of other minerals that share the same chemistry, but have different crystal structures. If positive identification between these minerals can not be made by field methods, then the specimen may simply be referred to as a potassium feldspar or Kspar .

University 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 highergrade metamorphic rocks.

What is Feldspar? (with pictures)

Jan 13, 2019· The distinguishing feature of minerals in the feldspar group is that they are comprised of silicates of aluminum blended with other metals like potassium, calcium, sodium, and sometimes barium. The composition of an individual piece determines its chemical properties and what color it will be, but it shares similarities with other feldspars ...

Orthoclase ( Potassium) feldspar

Orthoclase is the characteristic potassium feldspar of igneous rocks, occuring both alone and in perthitic intergrowth with albite; it also occurs in some metamorphic rocks. The variety adularia is formed at comparatively low temperatures, typically in veins.

Gallery of Feldspars ThoughtCo

Feldspars lie along one of two solidsolution series, the plagioclase feldspars and the alkali or potassium feldspars. All of them are based on the silica group, consisting of silicon atoms surrounded by four oxygens. In the feldspars, the silica groups form rigid threedimensional interlocking frameworks.

Feldspar Wikipedia

Feldspars crystallize from magma as veins in 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.
