摘　　要：在综合研究区域地质、地球物理、地球化学异常特征基础上,通过对乌尔沟地区进行1∶5万水系沉积物测量,查明了乌尔沟地区赋矿地层为蓟县系卡瓦布拉克岩群和上泥盆统天格尔组;控矿构造为冰达坂韧性剪切带;围岩蚀变以硅化、黄钾铁矾化、钾化、孔雀石化、蛇纹石化为主,矿化以白钨矿化、碳化为主;圈定了莫德图金铜石墨找矿靶区(B-2)和国光北钨钼找矿靶区(A-1),构建了乌尔沟地区地质-地球物理-地球化学综合找矿模型,为进一步找矿工作提供了新思路、新方向。On a comprehensive basis of the characteristics of geological,geophysical and geochemical anomalies,the 1∶50000 stream sediment survey in Wuergou area was carried out,finding that the ore-bearing strata in Wuergou area are the Kawabulake Rock Group of Jixian System and the Tianger Formation of Upper Devonian;the ore-controlling structure is Bingdaban ductile shear zone;the alteration of surrounding rock is mainly silicification,jarosite,potassification,peacock petrification and serpentine while the mineralization is mainly scheelite and carbonization;the prospecting target area(B-2)of Modetu Au-Cu-graphite and the prospecting target area(A-1)of Guoguang North tungsten-molybdenum are determined,and the geological-geophysicical-geochemical comprehensive prospecting model is constructed,providing a new idea and direction for next-step ore prospecting work.
