内蒙古阿尔善地区土壤地球化学异常特征及找矿意义

Soil geochemical anomalies and prospecting significance in Alshan region of Inner Mongolia

内蒙古呼伦贝尔市阿尔善地区位于兴安岭成矿带西伯利亚板块南缘东乌旗早华力西褶皱带(Ⅱ2)内。区内矿产资源丰富,主要有铁、铅、锌、银、铜、金、钼多金属等重要矿产的资源。本次1:5万土壤地球化学测量以取得显著的地球化学普查信息为基础、以勘查地球化学理论、区域成矿理论和遥感地质理论并结合已有物化探成果为指导,在综合分析研究调查区地质、矿产、区域地球化学、地球物理异常和遥感特征以及前人勘查地球化学方法技术试验成果的基础上,结合区内自然地理和地球化学景观条件,全面评价区内矿产的资源潜力,为进一步地质找矿提供坚实的地球化学依据。

Alshan of Hulunbeir is located in the Siberian plate,Mountains forming the south edge of the Dongwu Banner,early Variscan fold belt（Ⅱ 2） inside,Xinganling metallogenic belt.There are rich in mineral resources in the study area,mainly iron,lead,zinc,silver,copper,gold,molybdenum poly-metallic minerals and other important resources.The 1：50,000 soil geochemical survey in order to obtain significant geochemical survey based on information theory to exploration geochemistry,regional metallogenic theory and remote sensing combined with existing geological and geophysical and geochemical results of the theory as a guide,a comprehensive analysis of research studies in geological,mining,regional geochemical,geophysical and remote sensing abnormal characteristics and previous geochemical exploration methods and techniques on the basis of test results,combined with the natural landscape of the geographical and geochemical conditions,a comprehensive evaluation of mineral resource potential of the region,as further geological exploration geochemistry provide a solid basis.
