前言青藏高原位于地球上一个特殊的部位,因此,它具有独特的地质背景及演化历史,而花岗岩类岩石的微量元素特征是其演化的最明显标志。各旋回、各类型的花岗岩中的锶、氧同位素是反映其成因类型的重要因素之一。本文以锶、氧同位素资料探讨了青藏高原南部花岗岩的成因分类,并与世界较典型的花岗岩进行对比,其中许多数据为首次发表。 Preface Qinghai-Tibet Plateau is located on a special part of the earth. Therefore, it has a unique geological background and evolution history. The trace element characteristics of granitic rocks are the most obvious signs of its evolution. Each cycle, various types of granite in the strontium and oxygen isotopes reflect the type of one of the important factors. In this paper, the genesis of granites in the southern Qinghai-Tibet Plateau is discussed with strontium and oxygen isotope data and compared with the typical granites in the world, many of which are published for the first time.
