What is the Difference Between Feldspar And Quartz?
Feldspar has a lower hardness (6-6.5) compared to quartz (7) on the Mohs scale. Additionally, feldspar comes in a variety of colors including white, pink, brown, and gray, while quartz is predominantly colorless but can also come in different shades of white, yellow, pink, and brown.

Feldspars
Albite and K-feldspars occur also in a high temperature granite body cap called greisen. Greisens are complex rocks, integrating both magmatic and hydrothermal phenomena. Between the magmatic granite body and greisen cap is usually a layer of extremely coarse grained crystals of K-feldspar, quartz and zinnwaldite mica.
