【 摘 要 】

porphyry molybdenum deposit is one of important molybdenum deposit types in the world, and the quantity of molybdenum resources accounts for 90% of global molybdenum resources. In recent decades, important progress has been achieved in terms of geologic features, geochemical features, mineralization metal resource, mineralization fluid resource and evolution of porphyry molybdenum ore as well as Mo element migration and sedimentation mechanism, mineralization age clarifying and geochemical dynamics of deposit formation. Based on synthesizing predecessors' achievements, mineralization metal resource and mineralization chronology are introduced in this paper, and new materials are provided for the research on porphyry molybdenum ore. The research indicates that, provenance system of porphyry molybdenum ore is very complicated, and Re-Os and Os-Os are effective age measurement methods.
