摘　　要：为研究博格达晚古生代铜矿成因类型及找矿方向,以该地区开展的1∶5万甘河子区调项目为依托,通过开展1∶5万水系沉积物测量、1∶1万地物化综合剖面及探槽工程,对东台子铜矿化点特征进行了研究。该铜矿点1∶5万化探显示有Hs-18乙3类异常,异常元素组合为Au-Ag-Zn-Pb,具三级浓度分带,主成矿元素为Au、Ag,元素套合较好。Au均具三级浓度分带,Ag具二级浓度分带。1∶1万地物化综合剖面显示,Zn呈强富集分布,Au呈富集分布,Fe呈高背景分布。铜矿化体产于柳树沟组第三段(C2l3)火山岩中。矿体长大于50 m,厚0.4~0.8 m,走向北西-南东向,倾向北东,Cu品位0.019%~0.15%。成因类型为构造-火山岩型。In order to study the genetic type and prospecting direction of the Late Paleozoic copper deposit in Bogda,based on the 1∶50000 Ganhezi regional survey project carried out in this area,the characteristics of Dongtaizi copper mineralized spot were studied by carrying out 1∶50000 stream sediment survey,1∶10000 geophysical and geochemical comprehensive profile and exploration trench project.The 1∶50000 geochemical exploration of this copper mineralized spot shows Hs-18 B3 type anomalies.The anomalous element combination is Au-Ag-Zn-Pb,with a three-level concentration zoning.The main mineragenetic elements are Au and Ag,and the element nesting is better.Au has a three-level concentration zoning,and Ag has a two-level concentration zoning.The 1∶10000 geophysical and geochemical comprehensive profile shows that Zn is strongly enriched,Au is enriched,and Fe is distributed at high background.The copper mineralized body occurs in the volcanic rocks of the third section of Liushugou Formation(C2l3).The ore body is more than 50 m long and 0.4~0.8 m thick,with strike of NW-SE and dip direction of NE,with a Cu grade of 0.019%~0.15%.The genetic type is tectonic-volcanic rock type.
