综合方法在内蒙古杭盖音浑迪浅覆盖区寻找隐伏矿床中的应用

摘要

The Hanggaiyinhundi area of Inner Mongolia is seriously covered and indistinctly prospected.The au-thors have summarized the previous research on the basis of comprehensive ore-prospecting information and com-pleted some work on launched geological mapping,soil geochemical measurements,intermediate gradient in IP measurement according to the practical situation.This method helps decrease the effective cost and receives good prospecting results by drilling verification,so the objective of comprehensive prospecting was achieved.This study was based on mutual authentication system and focused on the effects and problems of the work in this research ar-ea.Finally,the geology-geochemistry-geophysics integrated prospecting models were established through compre-hensive analysis of regional geology background,geological characteristics,geochemical characteristics,geophysi-cal characteristics and source materials for mineralization,host space and ore-controlling structure and prospecting indicators.%针对内蒙古杭盖音浑迪地区覆盖严重、找矿信息不明显的情况，在总结前人相关综合信息找矿的基础上，根据研究区的实际情况，选择性、分阶段地开展地质填图、土壤地球化学测量、激电中梯测量工作，有效地节约了成本，且钻探验证找矿效果理想，达到了综合找矿的目的。着重介绍该研究区开展的各项工作所取得的效果及存在的问题，以相互认证体系为基础，综合分析区域地质背景、地质特征、地球化学特征、地球物理特征，对成矿物质来源、容矿控矿构造及找矿标志进行了研究，最终建立地质－地球化学－地球物理综合找矿模型。
