Orthoclase: Mineral information, data and localities.

Orthoclase is the most common member of the series, being the dominant K-feldspar in most granite, granitic rocks and other plutonic rocks, with an intermediate cooling regime. Despite the enormous number of reports of orthoclase in granite pegmatites, orthoclase is rare in pegmatitic pockets. It has, however, been known to be stabilised by ...

Alkali Feldspar

Alkali feldspars constitute a solid-solution between K-feldspar or orthoclase molecule (Or) and albite (Ab), which represents also the sodic end-member of the plagioclase series. Anorthite (Ca[Al 2 Si 2 O 8]; An) is present in small quantities in alkali feldspars, usually constituting less than 5% of the solid solution and predominantly found in Na-rich alkali feldspars.
