Geological Characteristics And Prospecting Prediction Of The Wukuaidaigou Gold Deposit In Wulateqianqi Of Inner Mongolia

The research area is located in Dashetai town of Bayannaoer Inner Mongolia.The co nclusion is based on collecting previous data and field geological survey,then research by using geophysics,geochemistry and other means.The paper summarizes the geological chara cteristics of ore bodies,discusses the genesis and metallogenic mechanism of ore bodies,a nalyzes the metallogenic geological conditions,puts prospecting indicators,and establishes a typical comprehensive information prospecting model.Through the above,The paper pre dicts hidden ore bodies and validates engineering implementation.The geological study of the deposit shows that the strata in the study area are mainly the East Five Molecular Formation?Ar₃d?of the Neoarchean Seltengshan Group,the Wudanggou Formation?J₁-₂w?,the Changhangou Formation?J₂c?and the Quaternary Alluvial-diluvial deposits(Qh^al+pl)of the Mesozoic Shigai Group.They are developed in early Yuan Dynasty,with gneiss black cloud plagioclase granite and medium fine grained granite.The structure of the study area is mainly faulted structure,followed by fold struct ure.The faulted structure is mainly NW-trending and NEE-trending faulted structure,follo wed by NEW-trending faulted structure.The NW-trending faults are the main ore-conductin g and ore-controlling structures in this areaThe gold ore bodies is in the second member of the East Five Molecular Formation of the Neoarchean Seltengshan Group.The ore bodies are controlled by structure and vein ed.Ore minerals are mainly pyrite and gold,gangue minerals are quartz,mica,feldspar.E pigenetic minerals are limonite and so on.The genetic type of ore body is metamorphic h ydrothermal deposit.Analyzing the metallogenic geological conditions,theyare most closely related to the f ault structures and mineralization.Under the guidance of metallogenic prediction theory,thi s paper combined with the prospecting information geophysical and geochemical methods,t hen predict the concealed orebodies and verificate.There are two gold orebodies with aver age tastes of Au:4.94 g/T and Au:5.05 g/T.The quantity is 32918.65 tons,and the metal quantity is 181.77 kilograms on predicting intrinsic economic resources?334??.The results show that it is feasible to apply typical ore deposit prospecting model andcomprehensive information prospecting method in the prediction of concealed orebody,It has great significance for further prospecting work in the study area.
