The Inner Mongolia Dalaiaobao Copper And Molybdenum Tectonic Ore-controlling And Ore Controlling Model Research

Through the features of ore control structure of orebody Dalai aobao copper molybdenum deposit in the study area as the research object, discuss in detail the basic pattern, structural ore controlling tectonic characteristics and deep prospecting and other issues of the study area, put forward the ore controlling model structure of the area, at the same time to research the source of ore-forming materials and ore-prospecting criteria are summarized and inductive.Previous geological prospecting methods in this study area are exposed to the surface of quartz vein type gold Au-Pb-Zn orebody for shallow controlling and disclosure,the deep copper molybdenum porphyry orebody understanding and study of the potential disadvantages, prospecting the low efficiency. The research work in this paper by means of geological data obtained in the beginning, by the field investigation work, the deep porphyry ore controlling tectonic characteristics and mode and discuss preliminary study with a view which ore prospecting work in this area in the future put forward deep prospecting model and an effective method.The new method to geological survey and other modern prospecting theory as the guiding ideology, through field investigation, has carried on the analysis model of ore control features of ore control structure of the study area shallow ore bodies and deep concealed ore body structure, Through these work,this paper concludes the following results:The fracture of North East, North and south is the study of the ore controlling fault in this area, it is because of fracture development scale, fault structure, internal structure of ore fluid properties and migration conditions and other differences, led to the uneven distribution of mineralization, mineralization period of enrichment phenomenon appeared. The quartz vein limonite that filling in the North East, North and south fracture is the directly sign of prospecting marks. Through research that the Dalai aobao ore deposit has typical porphyritic mineralization characteristics,two complicated mineralization shapes from upper and lower has showed in this mineral deposit, shallow ore bodies has been controlled by fault structure of ore control features clearly, deep faults has been controlled the fine grain adamellite output for the mineralized porphyry which is also the ore-forming mother rock.The researching concludes that prospecting for Cu-Mo porphyry orebody, essentially put forward for deep prospecting in the study area, has been convinced that the analysis combined with the geophysical anomaly and ore control structure, deposit model elaboration, in mine of the intersection body swollen parts is a prospecting way, it is worth exploring.The research of the ore controlling tectonic characteristics and structures in the area of the ore controlling model has important guiding significance for geological prospecting work in this area, the paper proposed the ore controlling model knowledge and achievement also has certainly been referenced value for the adjacent area of geological exploration working.
