FELDSPARS
feldspars. feldspars.
One physical property that distinguishes plagioclase feldspars from orthoclase feldspars is their cleavage. Plagioclase feldspars typically exhibit good cleavage in two directions at right angles, while orthoclase feldspars show perfect cleavage in one direction. Another distinguishing feature is their color. Plagioclase feldspars are usually white to gray, while orthoclase feldspars can be white, pink, or other colors.
No. Feldspars and hematite are examples of minerals.
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
Feldspars are classified as silicate minerals.
White
Feldspars are the first to crystallize at the eutectic point after which the temperature drops, thus crystallizing the iron - magnesium.
Quartz and feldspars are the most common silicate minerals of the crust.
