摘要
安徽省石屋岩体和岑山岩体在地质产状、形成时代及岩石学特征上十分相似 ,前人将其划为同一单元 ,并一直将其定名为黑云母斜长花岗斑岩。通过岩石化学、岩相学及矿物学研究认为石屋岩体及岑山岩体应定名为花岗闪长斑岩。
The Censhan intrusion is much similar to the Shiwu intrusion in field occurrence,formation time and petrological characteristic.It was reported that they were the same unit,and all the time denominated biotite plagioclase granite porphyry.The research on the petrochemistry,petrography and mineralogy of them indicates that the Censhan and Shiwu intrusions should be named granodiorite porphyrite.The plagioclase is a special type of granite in chemical composition,which format in the special tectonic setting.
