摘要/Abstract

摘要： 西藏扎西康铅锌多金属矿床位于喜马拉雅碰撞造山带东段的多金属成矿带内。为探明该矿床控矿构造的电性特征，笔者在矿区布设两条地球物理（音频大地电磁AMT、大地电磁MT）测线进行数据采集，并经过详细的数据处理和反演计算，得到较好的地下电性结构剖面。结合长期野外调查和物性、钻孔资料，解译出9条断裂，其中包含4条含矿断裂和4条隐伏断裂，1个深部隐伏岩体，划定2个深部有利找矿点（即F_t2和F₂₄断裂深部）。

Abstract: The Zhaxikang Pb-Zn polymetallic deposit is located in the polymetallic metallogenic belt of the eastern section of the Himalayas. In order to determine the electrical characteristics of the ore-controlling structure of the deposit, the authors set up two geophysical (AMT, MT) survey lines in the deposit area for data collection and obtained a good underground electrical structure profile after detailed data processing and inversion calculations. Combined with long-term field surveys, physical properties and drilling data, 9 faults were interpreted, including 4 ore-bearing faults, 4 concealed faults and 1 deep concealed rock mass, and 2 deep favorable prospecting points were delineated(deep fracture of F_t2 and F₂₄).

Key words: Zhaxikang Pb-Zn polymetallic deposit, geophysics, inversion, electrical structure, fault, prospecting prediction
