摘　　要：以青海天峻县维日可琼地区为例,在分析该区区域地质背景的基础上,结合区内1∶50 000水系沉积物测量成果,圈定了AS17乙_3(Au-As-W-Mo-Cu-Ag)、AS18乙_3(Au-As-W-Mo-Ag)、AS22乙_3(Au-W-As)、AS10乙_3(Co-Cu-Pb-Mn-Ag-Sn-W-Ni)、AS16乙_3(Au-As-Pb-W-Cu-Mo-Bi-Sn)、AS15乙_3(Sn-Bi-Au)等综合异常,并分别从地层、构造、岩性特征等方面对各异常进行了剖析评价,并进行了异常查证,从而圈定了2处找矿靶区,即维日可琼西A类金找矿靶区和维日可琼B类金多金属找矿靶区。综合评价认为,该2处找矿靶区金矿找矿潜力较大,可进一步开展异常查证工作,扩大找矿线索,有望取得找矿突破。Taking the Weirikeqiong Area in Tainjun County,Qinghai Province as the study example,in order provide some reliable basis for the prospecting and exploration work of polymetallic deposit in the area,the 1∶ 50 000 stream sediment survey work is conducted in the area,based on the stream sediment survey results in the area,the comprehensive anomalies of AS17（ Au-As-W-Mo-Cu-Ag）,AS18（ AuAs-W-Mo-Ag）,AS22（ Au-W-As）,AS10（ Co-Cu-Pb-Mn-Ag-Sn-W-Ni）,AS16（ Au-As-Pb-W-Cu-Mo-BiSn） and AS15（ Sn-Bi-Au） are delineated,and they are evaluated and analysis from the aspects of strata characteristics,tectonic characteristics and lithologic characteristics,and the anomaly verification of them are conducted respectively,and two prospecting targets are delineated（ A-type gold deposit prospecting target area of the west of Weirikeqiong Area,B-type Au-polymetallic prospecting target area of Weirikeqiong Area）. The resources potential of the two prospecting target areas show that the gold deposit prospecting potential of them are both huge,it is necessary to conduct further anomaly verification of them,so as to expand the prospecting clues,and the prospecting berakthrough can be obtained in the area.
