近年来,在青海三江北段地区区域化探扫面工作基础上,实现了地质找矿的重大进展,三江北段已被国家地调局列为全国重要的、具有巨大找矿潜力的成矿带之一.在对主要异常的评价中,在二叠系地层中相继发现了旦荣、车拉涌、开心岭、陆日格、乌葱察别、东莫扎抓、纳日贡玛、众根涌、然者涌等铜、铅、锌、银矿床,而且这些矿床所取得的成果已显示出大-超大型矿床的找矿潜力.青南地区分布有大面积的二叠系含矿地层,通过对晚古生代地质构造环境的初步了解,对海相火山-侵入有关的铁矿、玄武岩有关的铜矿、火山岩有关的铜铅锌矿三组成矿组合进行探讨,组成了一个“唐古拉地块沱沱河-杂多石炭、二叠纪沉降带沉降期海相火山型铜、铅、锌、银、铁成矿系列”,通过成矿系列的研究,为今后该地区的地质找矿工作提供参考意见.%In recent years significant advances had been predicted on geological exploration in Qinghai. The northern segment of Sanjiang belt were classified as metallogenic belt of enormous potentiality by China Geological Survey. Through appraisal of the main anomalies, a series of Cu-Pb-Zn Ag ore deposits were found in Permian, suchu as Danrong, Chelarong, Kaixinling, etc.. The discovery of the deposits revealed to enormous potentiality in the area. After Analysis on iron ore related with volcano intrusive rocks, copper ore related with basalt and Cu-Pb-Zn ore related with volcanic rock, a metallogenic series of Cu-Pb-Zn-Ag ore deposits were established as marine volcanic type in Tanggula area. Through the research of this metallogenic series, guiding significance can be found for further geological prospecting work in the area.
