大兴安岭南东段银铅锌多金属矿床地质特征与找矿模型——以喇嘛罕矿床为例

重点查明了喇嘛罕Ag-Pb-Zn多金属矿床地质特征、成矿地质条件和控矿因素，采用多种地球物理扫面-测深技术，对矿化脉和预测区段进行精细的三维地球物理勘查，探测矿化地质体空间分布规律及其规模。总结出了该地区的成矿规律和地质找矿标志，建立了成矿模型和找矿勘查模型，对指导区域找矿具有重要的意义。并通过少量的地表和深部工程验证地球物理勘查的成果，对矿区的资源远景作出评价。

Geological Features of Silver-Lead-Zinc Polymetallic Deposits in Southeast Section of Daxinanling-with Lamahan deposit as the case

The geological features，ore-formation conditions and ore-controlling factors of Lamahan Ag-Pb-Zn polymetallic deposit were identified.Several geophysical regional survey and depth sounding techniques were used in detailed 3D geophysical exploration of mineralized veins and forecasted areas to find the spatial distribution law and scale of mineralized geological bodies.The ore-formation law and geological ore prospecting indicators in this area were summarized and ore-forming and ore prospecting models were established，which are of important significance to guiding the regional prospecting.The geophysical exploration results were verified by small amount of surface and depth engineering and the resource prospect of this area was evaluated.
