黑龙江鸡东四山林场铜钼矿区地气地球化学找矿

Geogas geochemical prospecting of Sishanlinchang copper-molybdenum deposit in Jidong of Heilongjiang

对黑龙江东南部鸡东县四山林场铜钼矿区进行地气法测量,发现空白和测量样品差异明显。地气测量方法是通过采集、捕获来自土壤气体中的金属元素,并且这种采集和分析方法有效。地气测量在测区均发现了不同规模、不同强度的异常,元素组合主要为Ni、Cu、Pb、Zn、Sb、Mn、Co。沿DQ-1、DQ-2、DQ-3存在北东向地气异常带;沿DQ-4,DQ-3存在近东西向地气异常带;DQ-2,DQ-3,DQ-4似呈一环状,证明地气在本区应用的有效性。

Through geogas geochemical measuring of Sishanlinchang copper-molybdenum deposit in Jidong of southeast Heilongjiang,the authors found significant differences in blank and measured samples.Measurements of geogas geochemistry is the collection and capture of metallic elements of gas in soil,and this measurement of collection and analysis is effective.The anomalies of different-sized and intensity have been found in measuring.The element combinations are mainly composed of Ni,Cu,Pb,Zn,Sb,Mn and Co.They are mainly NE trending geogas anomal zone in DQ-1,DQ-2 and DQ-3,and nearly WE trending geogas anomalzone in DQ-4 and DQ-3.The zone of DQ-2,DQ-3 and DQ-4 looks like a ring in form,which evidenced the geogas measurement effective in the studied area.
