| 摘 要： | 灰池子花岗岩基主要由黑云斜长混合花岗岩和二长混合花岗岩组成。前者是加里东期的交代花岗岩;后者是在海西晚期钾交代作用再次改造先期岩石形成的。因此是一个由多次交代作用形成的混合花岗岩岩基。本文从构造地球化学的某些观点讨论这种岩石形成过程中钾元素迁移机制。

| Abstract: | Synthesizing the data from Hu Souxi et a1.(1988), Lu Xingxiang et al. (1989) and themself result, the authors consider that the Hueichizi granitic batholith in East Qinlhlg region is a transformation type of granites (corresponding to S-type). From the data on geochemistry, isotopes and trace elements, the biotite-plagioclase granite might be formed by the migmatization of the crustal materials in the Late Caledonian period and the adamillite-granite was probably formed by superimposition-replacement in Late Hercynian period. This model refJects not only the inheritance of source rocks, but also a multiphase reworking process. |
