The Qinggang molybdenum deposit is situated in the central of Zhouning-Huaan volcanic substrates fault-uplift belt and Zhenghe-Dapu fault zone.The ore body exists in veins-thin veins and exists in the low angle fractures of contact zone of Late Jurassic ancient Zhuchao unit K-feldspar granit and granit porphyry.Ore minerals are single molybdenite.Based on the wall-rock alteration and the discussion of metallogenic period,it is considered that the molybdenum deposit formation have the characteristics of post-magmatic middle temperature hydrothermal fluid.It is belong to the generalized porphyry molybdenum deposit.
