Gansu Province Chengxian Longdongwan Polymetallic Ore Deposit Ore Body Characteristic and Origin Brief Analysis

The Longdongwan polymetallic ore deposit geostructure is in middle the Kunlun Mountains Qinling folded region Qinling system of fold Li xian-Zashui Haixi geosyncline belt of folded strata.Is the Qinling thing to east the structural system and the Wudu arc structure wing's compound spot,it's east mine field of Xicheng,the Wujiashan anticline northern,the Changba,Lijiagou two large-scale lead-zinc mine bed's north west lengthens the spot.The geostructure position is extremely special,has the good mineralization environment and the mineralization condition.The article through to the home court ore deposit geological feature,the ore body characteristic,the ore characteristic and so on elaboration and the ore deposit origin shallow must analyze,thought that the deterioration hydrothermal filling metasomatosis is the mineralization primary factor,the faulted structure is controls the ore,mineralization the primary factor.The ore deposit strictly the contact strip,the rock association,the angle lithification belt,north to west,near thing the control which breaks to opens curving,has the multi-mineralization material to originate,characteristics and so on many phase of mineralization,pointed out that the ore deposit type is with the magmatic intrusion related deterioration hydrothermal filling confession ore deposit.
