Back to Rocks and Minerals Articles Kathy Feick x Al(Al,Si)3O8 (“x” can be sodium and/or calcium and/or potassium) Feldspar was officially given its name by Johan Gottschalk Wallerius in 1747. It is a contraction of the longer name fieldspar as some early specimens were found in fields. The term spar is a generic term used to refer to any non-metallic mineral with a vitreous
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.
Feldspar. Feldspar is the most common mineral on Earth, constituting approximately 60% of the crust.It forms directly from cooling magma and is a major component of granite and most other igneous rocks.. The term feldspar actually covers a whole family of minerals, all of which consist of a framework of aluminum, oxygen, and silicon atoms plus an additive, usually potassium, sodium, or calcium.
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 K-spar.Plagioclase feldspars lack potassium, are light colored and are usually striated.

Orthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is polymorphous with the minerals Microcline and Sanidine.These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis.

Apr 02, 2019· Feldspar is a very versatile material, and is used in a wide variety of products worldwide. Here in the United States where I live, over half of all feldspar in use goes to making glasswares, like dishes and windows and such. The remaining amount goes into things like rubber and plastic, where the feldspar serves as an extender and filler.

Feldspar’s physical properties of dispersibility, weatherability, scrub resistance, and mildew resistance make it attractive to the coatings industry. I-Minerals is focusing on potassium feldspar (K-spar). Deposits of high-quality K-spar that can be economically extracted are rare.
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.

Pronunciation: RYE•oh•light Specimen Pictures. Specimen 1; Specimen 2; Description*: Rhyolite is an extrusive igneous rock composed primarily of alkalai feldspar (e.g., the potassium-rich feldspar orthoclase, which commonly has a salmon pink color), sodium-rich plagioclase feldspar (which is commonly white to gray), and quartz (which is commonly colorless).
