Description
Discovered in 1747 by John Wallerius, plagioclase is an abundant mineral that can be found in igneous and metamorphic rocks. However plagioclase is not one mineral, but encompasses a range of minerals, whose names vary with the structure of its chemical formula. The end members of plagioclase are sodium rich albite and calcium rich anorthite with oligoclase, andesine, labradorite, and bytownite in between those two. Plagioclase has a variety of uses such as being a valued component of clays used in ceramics and a component in concrete. In geologic research, plagioclase also has a variety of uses, such as being used as an indicator of the provenance of sandstones.
