内蒙古自治区额济纳旗东部埋汗哈达等地区成矿地质条件与成矿规律分析

Analysis of ore-forming geological conditions and ore-forming laws in the eastern part of Ejina Banner,Inner Mongolia Autonomous Region,including Burying Khan Hada and other areas

研究区位于天山-北山成矿区,石板井-额济纳旗华力西成矿带,区内经历了漫长的地质演化时期,发育有多期多阶段构造岩浆活动,区域矿产丰富。本次论文研究工作依托于《内蒙古自治区额济纳旗埋汗哈达等四幅1∶5万区域矿产地质调查》项目,以埋汗哈达地区为研究对象,通过系统收集阅读前人在研究区地质、矿产、物化探及遥感地质工作成果,深入了解研究区地层、构造、岩浆岩分布及其地质特征,并结合对研究区内矿床(点)的详细调查研究与物化探综合信息的提取分析,深入揭示成矿地质条件,厘定关键控矿因素及找矿标志,总结成矿规律与成矿特征标志,构建综合信息找矿模型,指出本区找矿重点和方向,以期为区内进一步矿产勘查工作提供思路。

The research area is located in the Tianshan-Beishan metallogenic zone,the Shibanjing-Ejina Banner metallogenic belt.The region has undergone extensive geological evolution,experiencing multiple stages of tectonic and magmatic activities,resulting in abundant mineral resources.This study is based on the“1∶50,000 Regional Mineral Geological Survey in Ejina Banner,Inner Mongolia”project,focusing on the Maihanhada area.By systematically collecting and reviewing previous geological,mineralogical,geophysical,and remote sensing studies in the research area,we aim to deepen our understanding geological characteristics of stratigraphy,structures,igneous rocks.Through detailed investigation of mineral deposits(points),and the extraction and analysis of comprehensive information from geophysical-geochemical data,we seek to reveal the mineralization geological conditions,identify key ore-controlling factors and prospecting indicators,summarize the metallogenic regularity,construct a comprehensive information prospecting model,and subsequently carry out the evaluation of metallogenic potential areas in the Maihanhada region.The ultimate goal is to provide guidance for further mineral exploration in the area.
