沱沱河铅锌矿集区位于青海省西南部唐古拉山北坡，是全国设立的首批(47片)国家级整装勘查片区之一。该矿集区不仅是青海省铅锌多金属基地的核心区，也是三江北段成矿带最具找矿潜力的矿集区，其中已发现4个铅锌成矿带及40余处铅锌矿床(点)，矿集区内不同的地质单元显示了不同富集元素组合，各成矿带均以 Pb、Zn 为主要成矿元素，但伴生元素差异明显，三叠纪、二叠纪地层是区内比较重要的成矿层位。成矿流体具有低温、中低盐度、中低密度、低压、浅成等特点，具有多期次、多阶段及多来源的富集特点。沱沱河地区矿床规模的大小与异常的规模强度有着密切关联，几乎所有的铅锌矿床及矿(化)点均位于铅锌地球化学省范围内；在总结成矿地质条件的基础上，指出该矿集区有望成为一大型铅锌矿产资源基地，并划分了5处重要的找矿远景区，其中以纳保扎陇-多才玛-布玛浪纳铜铅锌找矿远景区最具寻找大型-超大型矿床的潜力。

Tuotuo river lead-zinc ore concentrated area,located in the north slope of Mount Tanggula, southwest of Qinghai Province,is one of the first national exploration areas (47 areas)fully equipped.The ore concentrated area is not only the core area of Qinghai lead-zinc polymetallic base,but also the ore concentrated area which has the most potential for ore prospecting at the north section of Sanjiang metallogenic belt.Among which it has found four lead-zinc metallogenic belts and more than forty lead-zinc ore deposits (spots).Various geological units in the ore concentrated area display different enriched element combination.Each metallogenic belt takes Pb and Zn as the main metallogenic elements,but their associated elements are different significantly.The Triassic and Permian strata are quite important metallogenic strata in the ore concentrated area.The ore-forming fluid has several characteristics,including low temperature, intermediate-low salinity,intermediate-low density,low pressure,hypabyssal feature and enrichment characteristics covering multi-phase,multi-stage and multi-source.The size of deposit scale in Tuotuo river region is closely associated with abnormal scale strength.Almost all lead-zinc deposits and ore (mineralization) spots are situated in the range of lead-zinc geochemical provinces.On the basis of summarizing ore-forming geological conditions,this paper indicates that the ore concentrated is expected to be one large lead-zinc mineral resource base.Moreover,it divides five crucial prospecting areas,where Nabaozhalong-Duocaima-Bumalangnai copper-lead-zinc prospecting area has the most potential for searching for large-ultra large deposits.
