| 摘 要： | 通过将赤峰元宝山区碱长花岗岩和二长花岗岩的地球化学数据与国内外各类型花岗岩对比和判别,认为内蒙元宝山区花岗岩属于A型花岗岩,具有富硅、富碱、贫钙镁,微量元素出现Sr,P,Eu,Ti的低谷,稀土配分模式曲线呈右倾、富轻稀土、典型的海鸥式等A型花岗岩特点。利用Eby A型花岗岩构造环境判别图解判断岩体为A1型,而且是与大陆造陆抬升有关的A型花岗岩类。

| Abstract: | Comparison of Yuanbaoshan alkali-adamellite granite with various type of granite at home and abroad and the discrimination diagrams show that the Yuanbaoshan granite belongs to A-type granite.It is rich in silicon and alkali,and poor in calcium and magnesium characterized by a low valley pattern of trace elements including Sr,P,Eu,and Ti and right decline REE pattern with high LREE,a typical seagull style.All of these characteristics comply with A-type granite.And it is discriminated the A1-type granite in ... |
