Abstract：The Laodinggou molybdenum deposit is located in Xiong'ershan area of western Henan Province, which is one of the important metallogenic belts of nonferrous metals such as gold, silver, molybdenum, lead and zinc in China, with frequent magmatic activities, developed fault structures and good mineralization conditions. The mineralized zone is controlled by NWW-trending faults and acid-intermediate intrusive bodies. K1 and K2 are the two main structural alteration zones, of which three industrial orebodies are in veins with stable thickness. The grade of Mo is 0.01×10-2-0.48×10-2. The NWW-trending mineralized alteration zone is a major structural prospecting indicator. Silicification and sericite are the main alteration symbols. Molybdenite, pyrite and chalcopyrite are the main mineralization signs. The orebodies are not closed in deep part, showing a good exploration prospect.
