Micro texture's contribution to coloring of alkali feldspar in Mannari and Ariake Granits

Abstract

Alkali feldspars in Ariake Granit have different in coloring, white and pink. And Alkali feldspars in Mannari Granit show pink color. Every these feldspars shows some degree in turbidity. This report reveals those turbid textures can cause color variation of alkali feldspars.
