Orthoclase (Orthoclase)
Orthoclase (Orthoclase). Orthoclase is a feldspar mineral and one of the most common rock-forming materials in Earth's crust. It is usually encountered within different types of granite, where it is responsible for the pinkish or lighter flecks in that rock. The iridescent gemstone known as moonstone is also a variant of orthoclase.
Mineral Sources of Potassium for Plant Nutrition | SpringerLink
Theoretical considerations based on the experimental determination of mineral dissolution rates indicate that nepheline dissolves 100 times more quickly than potassium feldspar, and this suggests that nepheline-bearing rocks are more effective as sources of K for plant growth than granitic rocks, even though these have higher K …
