Orthoclase Feldspar Data

Orthoclase Feldspar Data. Orthoclase feldspar is a potassium aluminum silie, and is commonly called "potassium feldspar" or simply "Kspar," given that the chemical symbol for potassium is "K." Orthoclase is common in igneous rocks such as granite, granodiorite and syenite, as well as in crackfilling igneous vein material (pegmatite).

Orthoclase feldspar

Orthoclase feldspar formation. A common constituent of most granites and also other felsic igneous rocks. It is often forms huge crystals and masses in pegmatite. Similarly, the pure potassium endmember of orthoclase forms a solid solution with albite. The sodium endmember (NaAlSi3O8), of plagioclase. While slowly cooling within the earth.

Feldspar var. Orthoclase

Albite is considered both a plagioclase and alkali feldspar. In addition to albite, barium feldspars are also considered both alkali and plagioclase feldspars. Barium feldspars form as the result of the replacement of potassium feldspar. Alkali feldspars. The alkali feldspars are as follows: orthoclase (monoclinic), — KAlSi3O8
