The Intergrowth textures occurred in Koheda Pink granite (KPG) pluton is perthitic, myrmakitic and granophyric, and the main characteristic feature of the granite is Porphyritic where orthoclase phenocrysts are enclosed in matrix of quartz and plagioclase. The perthitic intergrowths are characteristics of autometamorphic origin and the myrmakitic and micrographic are simultaneous intergrowths due to solid state reaction.

Abstract


The Intergrowth textures occurred in Koheda Pink granite (KPG) pluton is perthitic, myrmakitic and granophyric, and the main characteristic feature of the granite is Porphyritic where orthoclase phenocrysts are enclosed in matrix of quartz and plagioclase. The perthitic intergrowths are characteristics of autometamorphic origin and the myrmakitic and micrographic are simultaneous intergrowths due to solid state reaction.
