Occasionally, barium ions fill the large spaces in the frameworks of these minerals, but more frequently this role is played by ions of potassium, sodium, or calcium.

Sub-classified as alkali or plagioclase, their chemical composition may be expressed as combinations of its four components: celsian, anorthite, albite, and orthoclase. All of these minerals have a structure in which oxygen-containing tetrahedra are linked together. FTP, what are these silicate minerals, the most abundant in the earth's crust?
