Feldspar | Formula, Properties & Application
Feldspar is a tectosilicate mineral, referring to a class of silicate minerals built from tetrahedral molecules where silicon and oxygen atoms form a three-dimensional framework. Its chemical formula is often given as XAl1-2Si3-4O8, where X represents a combination of sodium (Na), potassium (K), calcium (Ca), or barium (Ba).

Rare earths: An essential part of the green energy revolution
Rare earth deposits are sometimes associated with fluorspar, an industrial mineral containing the element fluorine. Historically, the primary source for US fluorspar production was the Illinois Kentucky Fluorspar District (IKFD), which is located on both sides of the Ohio River in Southern Illinois and Western Kentucky.
Lithium concentration gradients in feldspar and quartz
Plagioclase feldspar grains with distinctive blue-grey cloudy cores and adhering glass selvedges were hand-picked from the 1–2 mm sieve fraction of a bulk sample of the phase 9 ignimbrite from a location at U18/890739. Additional examples of the feldspars from this sample were used in the study by Charlier et al. (2008).
