WebChemical composition: Rock-forming minerals have specific chemical compositions that distinguish them from other minerals. For example, quartz (SiO2) is composed of silicon and oxygen only, while feldspars (e.g., plagioclase and orthoclase ) are silicate minerals that contain additional elements like aluminum, sodium, and potassium. Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture", because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar. The gem known as moonstone (see below) is largely composed of ort…
