摘要
在大宝山矿区开展地质测量、物化探、地表工程等地质工作基础上,对研究区内元素地球化学特征进行了初步分析.对主成矿元素分布特征、相关性等分析表明,区内主成矿元素为W、Mo、Cu、Au,其中土壤测量异常规模较大、峰值高、富集系数高;成矿主元素Mo、Cu、Au等相关性好.在物化探工作成果基础上,筛选找矿靶区,并进行钻孔深部验证,取得了很好的找矿成果,提高了探矿潜力,并确定了船肚矿区北部、南部及大宝山东部三处找矿靶区.
Based on the geological work of Dabaoshan and peripheral area to carry out geological survey,geophysical and geochemical exploration and surface engineering,element geochemical characteristics are analyzed.The main metallogenic elements distribution characteristic,correlation analysis showed,main ore-forming elements have W,Mo,Cu,Au,the measurement of soil have large scale anomaly,high peak and high enrichment factor;the main mineralization elements Mo,Cu,Au have good correlation.On basis of geophysical and geochemical exploration work,screening prospecting target areas and deep drilling test achieved very good prospecting results,to improve the prospecting potential.The belly in the northern,southern,and Dabaoshan eastern three prospecting target area were ascertained.
