摘要
鹅湖岩体为S型花岗岩 ,具有结构和成分演化序列。运用岩石结构序列法 ,将其划分为 5个单元 ,归并为 1个超单元。按侵入体空间展布形式、岩体地质学、岩石学、构造等资料 。
The Ehu intrusion is composed of a continental crust transformation type (S-type) granite and displays a textural and compositional evolution sequence. With a rock textural sequential method, this granite is divisible into 5 units which are combined into one superunit. Based on the geometry of the intrusion, rock geology, petrology and techono-geochemistry, the author believes that the emplacement of this granite has been controlled by regional tensile stress.
