About Feldspar GroupHide

As a Commodity:
Feldspar is the name of a group of aluminium silicate minerals and is collectively the most common mineral group found on the surface of the Earth. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline.

In petrology the group is split into two major subgroups:

Alkali feldspar - feldspar minerals poor in calcium, and mostly rich in potassium. At high temperature the alkali feldspars form a series from sanidine to high albite; the series is incomplete at low temperature. Some workers include barium feldspars (celsian and hyalophane) and probably the rubidium feldspar rubicline, as alkali feldspars.

Plagioclase - the albite to anorthite series.

Feldspars may contain very minor amounts of OH groups, considered as defects (e.g., Yang et al., 2015).

Varieties of Feldspar GroupHide

AntiperthiteAn intergrowth of orthoclase (often as lamellae) enclosed in a plagioclase host. Result of an exsolution process (cf. also perthite).
CryptoperthiteA variety of perthite with lamella of submicroscopic thickness.
MesoperthiteA perthite with approximately equal amounts of alkali feldspar and plagioclase.
PerthiteAn intergrowth of albite or oligoclase with a microcline host, occasionally also with a orthoclase host. The intergrowths or exsolution lamellae of the albite are visible as white lines coursing through the K feldspar groundmass.
Common in granite pegma...
