MINING ROCKSTAR OF THE WEEK - FELDSPAR!!
“Feldspar” is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth’s crust. They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties. Common feldspars include orthoclase (KAlSi3O8), albite (NaAlSi3O8), and anorthite (CaAl2Si2O8) - "Geology.com"
