    www.britannica.com/science/microcline 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.
