| 摘 要： | 本文主要从大地构造环境、煌斑岩的空间分布及其硫同位素、微量元素和稀土元素组成等方面,探讨贵东花岗岩体中煌斑岩的成因.结果表明,煌斑岩与周围的壳型花岗岩不同源,形成煌斑岩的原始岩浆,应为幔源大陆拉斑玄武岩浆。

| Abstract: | Based on the distribution of lamprophyre veins, the eompositions of sulfur isotope,trace elements and REE of lamprophyre, and the geotectonic setting, this paper discusses the origin of the lamprophyre in Guidong granitic complex. The conclusion shows that the lamprophyre, which had a different source with the neighbouring crust-source granites, was resulted from mantle basaltic magma. |
