摘　　要：探讨云南腾冲地区箐口钼多金属矿床的地质特征与找矿标志,为指导找矿提供理论依据。通过对矿床的野外地质特征调查,并结合土壤地球化学异常以及地球物理磁异常的研究,发现箐口钼多金属矿床赋存于下古生界高黎贡山群上段的变质岩中,控矿岩体为喜马拉雅期花岗岩,矿石矿物主要为辉钼矿。辉钼矿呈细脉浸染状、脉状、细脉状、角砾状、斑点状产出,与石英脉和硅化密切相关。物化探结果显示,喜马拉雅期花岗岩与东部地区的高黎贡山群上段以及中部地区的变质岩捕掳体的接触带具有较高的异常特征。该矿床为石英脉型矿床,石英脉和硅化蚀变带为该区最直接的找矿标志之一,具有物化探高异常特征的岩体接触带可作为间接找矿标志。The geological characterisdcs and prospecdng indicators of the molybdenum polymetallic deposit in the Jingkou area of Tengchong County, west Yunnan Province, are discussed and the theoredcal basis for the prospecdng work is provided. Jingkou molybdenum polymetallic deposi＇t occurs in the metamorphic rocks of Lower Palaeozoic Gaoligongshan Group, and the ore is hosted inthe granite of Himalayan Period. The investigation shows that the ore minerals in the deposit are mainly molybdenite, which appears as veinlet disseminated, veined, brecciated and maculosed ores, and quartz veins and silicification are closely associated with the Mo mineralization. This ore deposit belongs to quartz vein type deposit, quartz vein and silicified alteration zone are the most direct prospecting indicators, while the contact zone of rock mass with highly unusual anomaly is the indirect prospecting mark.
