近年来兴蒙造山带陆续取得找矿突破,通过对内蒙古扎嘎乌苏地区矿产地质预查,在分析区域成矿地质特征的基础上,开展了多尺度土壤(岩屑)地球化学测量,包括Au、Cu、Ag、Zn、Pb、As、Sb、Bi、W、Sn、Mo、Fe 12种元素,运用地球化学参数统计、聚类分析及因子分析等方法对调查测量数据结果进行多元统计分析,采用不同岩性分区异常下限衬值法圈定地球化学异常,进一步进行因子叠加,圈定综合异常4处,通过槽探等工程手段进一步了解了矿点特征,为扎嘎乌苏地区下一步找矿工作奠定了基础、指明了方向.
Geochemical characteristics and prospecting significance of Zhagawusu area in Inner Mongolia
In recent years,breakthroughs have been made in mineral exploration in the Xingmeng orogenic belt.Based on the geological pre survey of mineral resources in the Zhagawusu area of Inner Mongolia and the analysis of regional mineralization characteristics,multi-scale soil(rock fragment)geochemical measurements were carried out,including 12 elements such as Au,Cu,Ag,Zn,Pb,As,Sb,Bi,W,Sn,Mo,and Fe.The survey data results were subjected to multivariate statistical analysis using methods such as geochemical parameter statistics,cluster analysis,and factor analysis.Different lithological zoning anomaly lower limit lining methods were used to delineate geochemical anomalies,and factor superposition was further carried out to delineate 4 comprehensive anomalies.Through engineering methods such as trenching,the characteristics of mineral deposits were further understood,providing a basis for the next step of mineral exploration in the Zhagawusu area.Established the foundation and pointed out the direction.
