Feldspar is a highly diverse group of minerals and is one of the most abundant components of the Earth's crust. Feldspar minerals are classified into two main categories: potassium feldspars, such as orthoclase and microcline, and plagioclase feldspars, which include minerals such as albite and anorthite. Feldspars play a crucial role in petrology, the study of rocks, as they are present in many igneous, metamorphic, and sedimentary rocks. In igneous rocks, such as granite, they are often associated with quartz and mica, forming the main matrix. Plagioclase feldspars, for example, are often present in basalt and gabbro, while potassium feldspars are more common in granitic and syenitic rocks. The physical properties of feldspars, such as their vitreous luster, perfect cleavage, and hardness on the Mohs scale, which is generally around 6, make them distinctive. Feldspars can exhibit interesting optical phenomena, such as adularescence in moonstone, a variety of feldspar.
