Discussion About the Origin of Mineral Textures in Granite

The origins of small platy albite minerals in Li-F granites, various types of myrmekite, perthitic albite, antiperthite, K-feldspar megacryst are comprehensively discussed and reasonably explicated in accordance with metasomatic rule and contact relationship. It is possible to find out the history of superimposed metasomatic processes in granites. The dissolution-vug-filling process does not belong to metasomatism, but it is closely accompanied by intense replacement process. Metasomatic texture should be distinguished from other ones. Metasomatic relics also should be determined as real residue from the replacement seen at present rather than an inherited relict from the previous replacement.
