THE FELDSPAR GROUP Amethyst Galleries Mineral Gallery

The potassium or K-feldspars are polymorphs, meaning they have the same chemistry, KAlSi3 O8,but different structures and therefore are different minerals. The plagioclase feldspars are a set of minerals that are in a series from a sodium rich end member, albite, to a potassium rich end member, anorthite.

Aug 10, 2019· Alkali feldspar (also called potassium feldspar or K-feldspar) has a color range from white to brick-red, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing.

Potassium feldspar Wikipedia

Potassium feldspar refers to a number of minerals in the feldspar group, and containing potassium: . Orthoclase (endmember formula K Al Si 3 O 8), an important tectosilicate mineral that forms igneous rock; Microcline, chemically the same as orthoclase, but with a different crystalline structure; Sanidine, the high-temperature form of potassium feldspar (K,Na)(Si,Al) 4 O 8

Plagioclase: The mineral Plagioclase information and pictures

The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as individual minerals, whereas
