The feldspar perthites have always been of great interest to geologists. Although a mineralogical problem it is related to the formation of the alkali feldspars, and thus of great petrological significance. The feldspar relations, when thoroughly understood, will be a tool of the highest value in the understanding of rock forming processes.
