内蒙古包尔敖包地区岩浆岩地质特征及地球化学特征分析

Magmatic Rocks Geological Characteristics and Geochemical Analysis of Power-aobao Region in Inner Mongolia

以内蒙古包尔敖包地区岩浆岩为例,从侵入岩的地球化学特征、构造环境分析、侵入时代讨论和就位机制探讨方面分析包尔敖包地区侵入岩演化过程及演化特点;利用主量元素和微量元素及稀土元素数据编制、硅碱图、火山岩Ol-Ne-Q图解、火山岩ALK-FeO-MgO图解分析该地区上石炭统白山组火山岩岩浆活动环境及地球化学元素异常特征。

This paper,taking aobao areas within magmatic rocks for example,has made rock geochemical characteristics in tectonic environment. The author opens a discussion to put in place themechanisms by exploring Power aobao region in its characteristics of intrusive rock evolution. It uses main elements,including trace elements, rare earth element data preparation, silicon base figure, volcanic Ol-Ne-Q diagram, volcanic ALK- FeO-MgO style illustrations to analyze the region on the carboniferous Baishan groupvolcanic magma activity in environment and geochemical anomaly characteristics of the elements.
