Abstract:

Chengde area is located in molybdenum(copper) polymetallic metallogenic belt controlled by EW，NE and NNE trending fault in middle north margin of North China platform.Several deposits have been successively found in this area，such as Sadaigoumen porphyry molybdenum deposit，Shouwangfen skarn Mo-polymetallic deposit and Dacaoping vein type molybdenum deposit，which shows that this area has a good ore-forming background and prospecting potential.These molybdenum deposits are associated with Yanshanian intermediate-acid granites in time and space.The deposits are usually distributed along the internal or external contact zone of the granite porphyry or in rock bodies.Based on sufficiently collecting and studying the existing data of the typical molybdenum (copper) deposits in Chengde area，combined with the former research results，this article systematically summarizes geological characteristics，deposit types and spatial and temporal distribution of molybdenum deposits in this area，prospecting direction and target in the future is also proposed.It has important significance for strengthening resources exploration and prospecting breakthrough of molybdenum deposits in this area.
