Mineral resource of the month: feldspar | U.S. Geological Survey
The article focuses on feldspar, a mineral that composes of potassium, sodium, or a fusion of the two, and its various applications. According to estimates by scientists, the mineral is present at 60 percent of the crust of Earth, wherein it is commonly used for making glass and ceramics. Global mining of feldspar was about 20 million …
Feldspar: Meaning, Properties, and Benefits You Should …
Feldspar crystals are mainly made up of potassium and plagioclase minerals that include Orthoclase, Microcline, Sanidine, Albite, Anorthite, Labradorite, and Oligoclase. Feldspars may be transparent, translucent, or opaque with blocky, prismatic, platy, or thin crystals. They show various lusters, like waxy, dull, pearly, resin-like, or greasy.
Potassium Feldspar Group
Potassium feldspar group. Group name for three very closely related minerals: Orthoclase, Sanidine, and Microcline. These three feldspar minerals have equal physical properties. They are all composed of the same element s, but their crystal structure differs. It is sometimes impossible to tell apart one of these minerals from another without x ...
