The Mineral orthoclase. Orthoclase is one of the most common minerals, and occurs in numerous mineral environment s. It is polymorphous with the minerals Microcline and Sanidine. These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis. The only difference between them is their crystal structure.rthoclase is one of the most common minerals, and is found worldwide. Only a select few localities are mentioned. The original Carlsbad twins were described from Karlovy Vary (Carlsbad), Bohemia, Czech Republic. Some of the best crystals come from Baveno, Piedmont, Italy, especially the famous Baveno twins.
