东秦岭潘河钼矿床位于东秦岭钼矿带西部,通过野外调查可知,矿床赋存于中元古界宽坪群多旋回沉积—喷发地层中,含矿岩性主要为大理岩、白云质大理岩和绿片岩.钼矿体受控于潘河背斜核部及两翼层间剪切破碎带中,具有多层平行排列的分布规律;钼矿的形成与发展主要受次火山活动与构造控制,是构造和火山活动共同作用和长期演化的结果,与区内广泛出露的隐爆角砾岩有关.研究认为,潘河钼矿的矿床类型为火山期后热液型,成矿时代为燕山晚期;指出应在矿区内多旋回沉积—喷发层间、磁—电异常和隐爆角砾岩层等深部有利部位寻找钼(钨)矿体.

@@@@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.
