| 摘 要： | 萨吾斯铅锌矿床位于西伯利亚板块南缘阿尔泰晚古生代活动陆缘的泥盆纪—石炭纪弧后盆地中。矿床赋存于下泥盆统康布铁堡组酸性火山熔岩、火山碎屑岩夹陆源碎屑岩及碳酸盐岩中,是与海相火山作用有关的铅锌矿床。矿区位于1∶5万水系沉积物测量圈定的Pb-Ag-As-Zn-Bi-Cu-Mo-Au-Sb-Co-Ni综合异常内,其中Ag、As、Pb、Zn异常套合较好,与矿体基本对应,特别是Zn异常中心与矿体位置完全对应。矿区激电异常具有低阻、高幅频率、多峰值的特征,与地表矿化蚀变带对应。磁异常与激电异常相对应,异常宽度小于激电异常。TEM测深工作在矿区圈定了3个TEM低阻异常,均处于Ⅱ号矿化蚀变带内。在综合分析矿床成矿地质条件、地球化学异常、地球物理异常特征的基础上,建立了该矿床地质-地球物理-地球化学找矿模式,对类似矿床的发现和评价能够起到借鉴作用。 |

| Abstract: | The Sawusi Pb-Zn deposit is situated at the southern rim of Siberia plate. The deposit is hosted in felsic volcanic flows, volcanoclastics interlayered with terrigenous clastics and carbonates of the Kangbutiebao Formation of Early Devonian. The deposit is genetically related with marine Ag-As-Zn-Bi- Cu-Mo-Au-Sb-Co-Ni geochemical anomalies, and single element anomalies, such as Ag, As, Pb and Zn, are nearly matched with the distributions of the orebodies, especially for Zn the anomalous center is almost coherent with the distribution of the orebodies. Geophysical anomalies also showed high values of chargeability, low resistivity, and matched well with ground mineralized/altered zones. The magnetic anomalies are matched well with the IP (Induced Polarization )anomalies, but its anomaly width is narrower than that of the IP. The sounding IP and TEM (Transient Electromagnetic Method)anomalous zones intersect three mineralized zones which are located on the No.Ⅱ mineralized/altered zones. After comprehensive analysis of geological setting, geochemical anomalous zones, geophysical anomalies of Sawusi Pb-Zn deposit, the geological-geophysical-geochemical model of the mineralization is established. |
