Orthoclase Feldspar

What Is Orthoclase? Orthoclase is a feldspar mineral with a chemical composition of KAlSi 3 O 8 It is one of the most abundant rock-forming minerals of the continental crust Orthoclase is most widely known as the pink feldspar found in many granites and as the mineral assigned a hardness of 6 in the Mohs hardness scale

Orthoclase ( Potassium) feldspar

Sanidine occurs in potassium-rich volcanic rocks such as rhyolite and trachyte Orthoclase is the characteristic potassium feldspar of igneous rocks occuring both alone and in perthitic intergrowth with albite it also occurs in some metamorphic rocks The variety adularia is formed at comparatively low temperatures typically in veins

ALBITE (Sodium Aluminum Silicate)

Albite is also an end member of the alkali or K-feldspars whose series ranges from pure NaAlSi3 O8 to pure KAlSi3 O8 This series only exists at high temperatures with the mineral sanidine being the potassium K rich end member At lower temperatures the K-feldspars will seperate from the albite in a process called exsolution

MICROCLINE Facts Information

The majority of the common feldspars fall into two groups the alkali feldspars (KAlSi 3 O 8 through NaAlSi 3 O 8 series) and the plagioclase feldspars (NaAlSi 3 O 8 through CaAl 2 Si 2 O 8 series) Microcline (KAlSi 3 O 8) is the low temperature pure potassium end member of the alkali feldspar
