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.

网页1998年7月19日 · Microcline is the form of potassium feldspar that is stable at the lowest temperatures. Its structure differs from that of orthoclase because of a different distribution of silicon and aluminum atoms in its aluminosilicate crystal framework. Microcline exhibits a variation in symmetry.
