May 25, 2020· Plagioclase feldspars lack potassium, are light colored and are usually striated. The other k-spar minerals are sanidine, microcline and anorthoclase . Orthoclase is the more common of the k-spars. The differences between these minerals are minor in hand samples. Subsequently, question is, is potassium feldspar the same as orthoclase? Potassium ...
Feldspars are generally light colored minerals, white or buff to gray in color. One species, microcline, may also be light brick-red or even the green to blue green variety called amazonite. Because their atomic framework has planes of weakness, feldspars exhibit good cleavage, breaking readily into blocky pieces with smooth sides.
