Potassium Feldspar Common Minerals - University of Minnesota
Potassium feldspars are a group of polymorphs, polymorphs being minerals that have the same chemical composition but slightly different crystal structures. Despite their different crystal structures, the potassium feldspars are very similar to one another in appearance, so in the field they are often identified simply as ‘potassium feldspar’.
