What color is plagioclase feldspar?
Subsequently, one may also ask, what color is Feldspar?
In general, potassium feldspars commonly have pink to reddish hues, while the plagioclase feldspars tend to be white or gray, but both mineral groups may exhibit similar colors, so the presence or absence of striations is more diagnostic.
Additionally, how would you distinguish between orthoclase feldspar and plagioclase feldspar if they are the same color? Plagioclase is usually white to light gray in color, although color is not a reliable mineral indicator. More definitive in distinguishing plagioclase from orthoclase is the presence of fine parallel lines called "striations" on plagioclase - these striations do not occur with orthoclase.
Subsequently, one may also ask, is plagioclase a feldspar?
Plagioclase is a member of the feldspar group (like orthoclase) and is a framework silicate. Plagioclase consists of a solid solution between the albite and anorthite end-members, and together with quartz is the most common of the rock forming minerals.
