Abstract:

Panhe molybdenum deposit is located in the western part of East Qinling molybdenum ore belt.The molybdenum orebody lies in the middle-proterozoic Kuanping group，a sedimentation-eruption formation generated from polycyclic evolution.The main ore-bearing rock types are marble，dolomitic marble and green schist.Panhe molybdenum deposit exhibits the characteristic of multilayer and parallel shape，which is chiefly controlled by Panhe anticline core and shear fracture stucture in its wings.The formation and development of molybdenum deposit are mainly influenced by subvolcanic activityand tectonic，and have close relationship with cryptoexplosion breccia that intergrowed with subvolcanic rocks.It is the results of the common effect and long-term evolution of the structure and volcanic activity.The Panhe molybdenum deposit belongs to hydrothermal type in late volcanic stage，and its metallogenic epoch is late Yanshanian.The results show that looking for the molybdenum (tungsten) orebody should be in the deep favorable positions which are polycyclic sedimentation-eruption formation，magneticly-electricly abnormaly and cryptoexplosion breccia layers mainly.

Key words: Geological characteristics, Prospecting direction, Panhe molybdenum deposit, East Qinling
