University of Minnesota's Mineral Pages: Plagioclase Feldspar

Plagioclase feldspars are a continuous mineral series in which calcium and sodium substitute for one another in the same crystal structure. Because they share a similar crystal structure, all the plagioclase varieties exhibit very similar properties and in the field are often only identified as 'plagioclase'. Plagioclase minerals are ...

University of Minnesota's Mineral Pages: Potassium Feldspar

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.
