摘要
通过内蒙古表生环境中元素相容性排序检验,认为1∶20区域化探普查成果能提供原生环境中各类地质信息,尤其是普查找矿信息。区域化探元素测试结果存在系统误差,通过数据调平处理,保证了化探数据的质量。ln(wCr×wNi×wCo)等图件提供的信息,可作为划分地质地球化学分区的主要依据之一,对基础地质研究有参考价值。在此基础上初步圈定了元素地球化学成矿预测区,为内蒙古自治区提供了有价值的普查找矿信息。
A compatibility test of the chemical elements in the surface environment of Inner Mongolia has revealed that the 1∶200 000 regional geochemical survey can provide all kinds of geological information in the primary environment,especially the reconnaissance and prospecting information.The geochemical data quality can be ensured through data leveling processing for eliminating the major systematic errors in the test results of regional geochemical elements.Information provided by maps,such as the maps of ln（wCr×wNi×wCo）,can be used to make geochemical divisions and also serve as valuable reference for basic geological study.Based on the regional geochemical map,the authors delineated geochemical metallogenic areas of chemical elements in Inner Mongolia,which could provide important information for geochemical metallogenic prognosis.
