Orthoclase is a mineral that belongs to the family of silicate minerals called feldspar.The deference between the feldspars and the other silicates is that the former contain a mixture of the following chemical elements: Potassium K, Calcium Ca and Sodium Na, in addition to the usual constituents of the quartz based minerals, such as Aluminum, Al, silicon Si and oxygen O. From Apatite in Rocks. Rocks that has formed from a melt, containing the chemical elements Si, Al, K, and O.
