Damendeli forest farm is located in the east Tianshan-Xing Mongolia orogenic belt,Hailar-Huma invasion volcanic rocks of the northern section of segment,the greater Hinggan mountains-north eastern Yanshan magma activity belt(?),for the greater Hinggan mountains volcanic rock belt take the root of Josiah river area(?),the greater Hinggan mountains middle variscan,Yanshan epoch,iron,zinc,tungsten,gold,lead,chromium metallogenic belt(?),Boctu-Undulating Tungsten,iron,zinc,lead,metallogenic belt(IV),molybdenum,lead,metallogenic geologic condition is superior.Paper deeply studied the features related to the ore prospecting geochemical exploration data and comprehensive information such as mining,summarizes the metallogenic regularities and prospecting indicators,and the gold,molybdenum,lead,zinc metallogenic prospective areas delineated and the prospecting target area selection,in order to find out the potential of mineral resources in the district.The geological survey in this area reveals that there are 12 volcanic and 4 intrusive units in the area,the geological bodies exposed in the region mainly have the lower cretaceous white and old formation and late carboniferous granite.Fracture part of the surveyed area is roughly divided into NE,NW,EW and NS fracture,four groups of main periods of faults are intertwined,and constitute the basic tectonic framework of the workspace,among them,the large(more than hundred kilometers)regional NE,NNE to deep fracture structure to control role in Mesozoic magmatic activity and the product distribution.The area of circle more than 30 elements combination abnormalities,including five key exception,Au,Mo,Ag-Zinc-Pb combination stacking the symbiotic characteristics of anomaly is significant,Mo,Pb,high value and is directly related to mineralization in the area.In the case of the abnormal area of Au-Mo and Ag-Zn-Pb combined elements,it is found that there is a magnetic anomaly phase box,and it is also verified that these areas are favorable areas for ore body occurrence.Through the Damendeli forest farm,ore-forming geological characteristics,geophysical and geochemical metallogenic characteristics of the study,and combined with the prospective area prospecting potential evaluation,the final optimized target alow temperature hydrothermal type lead-zinc deposit,a high temperature fluid molybdenum ore target area.The mineralization is closely related to the old volcanic rocks and the late carboniferous granites in the early cretaceous,and the NE to the fault structure is the main ore controlling and bearing structure.Combined with the characteristics of typical ore deposits in the region,this paper summarizes the rule of metallogenic alteration and the prospecting sign,and provides some technical and scientific basis for the prospecting work in this area.
