Potassium Feldspar | Common Minerals
Quartz: Quartz is a common mineral in many metamorphic and felsic igneous rocks that, like the potassium feldspars, also has a non-metallic luster and hardness greater than glass. Unlike the potassium feldspars, however, quartz does not exhibit cleavage, which easily distinguishes it from feldspar minerals.
Plagioclase Feldspar: A group of common rock-forming minerals
Plagioclase is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na (AlSi 3 O 8 ), to pure anorthite, Ca (Al 2 Si 2 O 8 ).
