Microcline - Wikipedia
网页Microcline (KAlSi 3 O 8) is an important igneous rock -forming tectosilicate mineral. It is a potassium -rich alkali feldspar. Microcline typically contains minor amounts of sodium. It is common in granite and pegmatites. Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase.

Microcline - Clark Science Center
网页Microcline is found in granite, granodiorite, pegmatite, syenite and related plutonic igneous rocks that cooled slowly at considerable depth. Due to the time needed to order the placement of Al atoms in the crystal structure, microcline is not found in volcanic rock, but is commonly found in high-grade metamorphic rocks.

网页Microcline is a very common rock-forming mineral. It belongs to the feldspar group. It is one of three K-feldspars (K means Potassium). The other two are orthoclase and sanidine. The chemical formula of K-feldspars: KAlSi 3 O 8, but they usually contain sodium as well which replaces potassium. Microcline with perthitic exsolution.
