摘要

The Gaotongling molybdenum deposit is located in the Wuzhishan fold belt of the South China fold system, South China Plate. Nine orebodies of economic value and five mineralized bodies which are approximately parallel to each other have been identified. Ores are mainly of sulfide quartz vein type and K-feldspar granite type. The Re-Os isochron age of molybdenite is 98.4±2.5 Ma, which coincides with the emplacement age of the Gaotongling granite intrusion. It is concluded that the deposit is a hydrothermal sulfide-quartz vein type deposit genetically related to Late Mesozoic (late Yanshanian) granitic magmatism.
