内蒙古巴彦琥硕-幸福之路地区花岗岩类岩石学特征

PETROLOGY OF GRANITOIDS IN THE XINFUZHILUBAYANHUSHUO AREA,INNER MONGOLIA

摘要: 本文是在巴彦琥硕幅、幸福之路幅1:5万区调工作基础上,试用花岗岩单元—超单元填图理论,吸收湖南地调所花岗岩填图经验,对该区巴彦琥硕复式岩体、幸福之路复式岩体进行划分,建立了巴彦琥硕序列。在此基础上讨论其岩石学、岩石化学、稀土及微量元素地球化学等特征。

Abstract: On the basis of the data of 1:50000 regional geological surveys,the Xinfuzhilu-Bayanhushuo composite granite intrusion may be divided into sequences and units.The authors establish the Bayanhushuo sequence that is composed of the Bayan Obo,Shaligaba and Chaganba units.The Bayanhushuo sequence is duscussed in terms of petrology,petrochemistry and rare earth element and trace element geochemistry.
