【摘要】 本文研究了桐庐和黄山两地不同成因花岗岩类岩体中碱性长石的出溶和超微双晶。结果表明,碱性长石的出溶和超微双晶同岩体的成岩温度、冷却速率以及岩体成因类型和碱性长石的化学成份有关,成岩期后的热作用对碱性长石的出溶和超微双晶产生改造和破坏。更多还原

【Abstract】 This paper studies the exsolution and supcrmicro-twin of alkali feldspar from Tonglu and Huangshan granites. The main results obtained indicate that the exsolution and supcrmicro-twin of alkali feldspar are to related to the temperature, cooling rate, gcnelic type of granite and chemical composition of alkali fcldspar.The exsolution and supcrmicro-twin of alkali feldspar can be destroyed by the thermal action after granite body is formed.更多还原
