中文摘要:
      那更康切尔北银多金属矿紧邻那更康切尔沟银矿床的北部,大地构造上位于东昆北岩浆弧东段,赋矿层位为上三叠统鄂拉山组,矿体受北北西向、近南北向的断裂构造控制。物探方法在构造和矿床的研究中有着重要的优势,文章结合青海省都兰县那更康切尔北银多金属矿预查激发极化法成果及已知地质资料,通过综合分析验证,三叠系鄂拉山组中,激电异常相对高阻、高极化地段已发现矿体,得出了激电异常与已知地质信息的验证对应关系,高阻高极化异常地段为重要的找矿标志,为那更地区矿床研究提供经验资料。
英文摘要:
      The North Nagengkangqieer silver polymetallic deposit is adjacent to the north of Nagengkangqieer silver deposit.Tectonically, it is located in the eastern part of the magmatic arc.The ore-bearing horizon is the late Triassic orashan formation, The ore body is controlled by NNW and nearly north-southern trending fault structure.Geophysical prospecting methods play an important role in the study of structure and mineral deposits. This paper introduced results of induced polarization method and compared with known geologic data in the north of Nagengkangqieer Silver Polymetallic Ore, Through comprehensive analysis, In the orashan formation of the Triassic,The ore body have been found in the IP anomalies relatively high resistance and high polarization regions, The verified correspondence between IP anomaly and known geological information is obtained, The anomaly of high resistance and high polarization is an important prospecting marker, which provides empirical data for ore deposit research in the Nageng area.
