摘　　要：研究区位于南巴颜喀拉-雅江Li-Be-Au-Cu-Pb-Zn-水晶成矿带南缘,区内发育三叠纪和侏罗纪岩浆岩,与铜铅锌锂铍等矿产资源关系密切,为进一步研究成矿带内各岩浆岩单元的含矿性,以九龙地区1:5万水系沉积物测量为基础,分析17种元素的特征参数、分布规律及演化特征。结果显示:研究区Cu、Cr、Ni呈强富集的分布;Co、W、Sn为富集分布;Cd、Mo、Sb、Bi、Hg属极不均匀分布;Au、W、As呈不均匀分布。W、Sn、Mo在三叠纪侵入体中呈强富集分布,Hg呈富集分布;Pb在侏罗纪富集分布。侏罗纪花岗岩与T_(2)zg大理岩接触带有寻找矽卡岩型铅锌多金属矿潜力。The study area is located in the southern margin of Li-Be-Au-Cu-Pb-Zn-Crystal metallogenic belt in South Bayan Har-Yajiang.Triassic and Jurassic magmatic rocks are developed in the area,they are closely related to copper,lead,zinc,lithium and beryllium.In order to further study the ore-bearing property of magmatic rock units in the metallogenic belt,the characteristic parameters and distribution of 17 elements were analyzed based on the 1:50,000 stream sediment survey in Jiulong area.The results show that Cu,Cr and Ni in the study area are highly enriched.Co,w and Sn are enriched and distributed;Cd,Mo,Sb,Bi and Hg are extremely distributed unevenly.Au,w and As are unevenly distributed.W,Sn and Mo are strongly enriched in Triassic intrusive bodies,while Hg is enriched.Pb was enriched and distributed in Jurassic.The contact between Jurassic granite and T2zg marble has the potential to search for skarn-type lead-zinc polymetallic deposits.
