Study On The Geoglogical Characteristics And Exploration Direction Of Gold Mineralization In Wuzhuerzhage Area,Urad Zhongqi,Inner Mongoulia

Wuzhuerzhage area is located in Wulatezhongqi,Bayannaoer City,Inner Mongolia,which is situated in the northern margin of the North China plate accretion zone and Baoyintu-Xilinhaote volcano type passive continental margin.And it is located in Inner Mongolia-Daxinanling metallogenic province,Chagancilao-Bayinhanggai Gold Metallogenic belt,which is regionally classified as Bayinhanggai Gold Mineralization,with superior ore-forming geological conditions.On the basis of the collection and study of the previous data,the geological,geophysical and geochemical prospecting methods have been used to find out the geological conditions of the strata,tectonics,magmatic rocks and geochemistry in the study area,and to find out the characteristics and occurrence rules of gold mineralization bodies.Based on the analysis of regional metallogenic geological background and the geological characteristics of adjacent mining areas,and after a thorough study of favorable geological conditions,such as geology,geophysics and geochemical characteristics in this area,the main achievements and understanding are as follows:1 ? Through the screening and sorting of 6 geochemical anomalies obtained by debris survey by predecessors in the study area,it is considered that the abnormal front halo elements of AS-3 are Sb and Hg,and the content of Au,Ag,Cu and Pb is higher,and the abnormal nesting of the elements is better.By using geochemical comprehensive profile measurement,surface channel exploration engineering verification,it is found that the geochemical anomalies are closely related to quartz veins and fractured alterat ion zones in the F3 fault zone.And 7 gold mineralization bodies are delineated after surface channel exploration engineering exposure and deep drilling engineering verification,which indicaes that AS-3 has good prospecting potential.2?Through deep drilling engineering,to control and verify the mineralized bodies found on the surface,It is found that the gold mineralization body in the study area is distributed in the F3 fracture zone of the northeast corner of the mining area.And its shape,occurrence and space position are strictly controlled by the F3 fault zone.The ore bearing lithology are mainly granitic clastic rock with quartz vein and altered rock.The hydrothermal alteration of ore bearing rocks is strong,which shows that it is greatly influenced by late magmatic hydrothermal.3?The prospecting marks in the study area are as follows:(1)Lithologic marks: The contact zone between late Proterozoic granite and Baoyin group formation in the study area and its quartz veins and alteration zones nearby are favorable areas for prospect ing.The carbonaceous black fault gouge and fault bearing sulfide silicified granite in the F3 fault zone are the gold marker beds in this area.(2)Structural marks: The NW fault F3 in northeastern part of the study area provides a channel for magmatic activity and hydrothermal migration,which is a good ore hosting structure.(3)The alteration mark of surrounding rock: Alteration develops silicification,sericite,pyrite mineralization,chlorinization,kaolinitization and carbonation,among which silicification and pyrite mineralization are closely related to gold mineralization in the study area.4 ? Through systematic analysis of regional metallogenic geological background,characteristics of adjacent typical deposits and ore controlling factors such as s trata,tectonics and magmatic rocks in the study area,it is believed that the F3 fracture zone in the northeastern part of the study area is often filled with ore quartz veins,not only the passage of ore fluid migration,but also the place of mineral fluid filling,and all the gold orebodies occur in the fault,which has good prospecting potential.
