Metallogenic Geological Conditions And Metallongenic Prognosis Of The Wanheyong Area In Chi Feng,the Inner Monggolia Autonomous Region

The study area is located in the southeastern part of the Keshiketeng County of Inner Mongolia Autonomous Region,and most of the area are under the jurisdiction of the Keshiketeng County of Chifeng City in the administrative divisions.The geotectonic location of the study area is located in the passive continental margin of the Xianghuangqi-Chifeng volcanic type of the accretion zone of the northern continental margin of North China.Also the study area is located in grade IV metallogenic belt of Tungsten,Gold,Molybdenum,Lead,Zinc and Copper of Dongzi-Tangjiazhangzi,Inner Mongolia,and grade V metallogenic belt of molybdenum,lead and zinc of Xiaodonggou-Liutiaogou metallogenic belt.At present,many copper,lead-zinc metal deposits,ore spots and mineralization sites have been found in the study area,which are favorable areas for the exploration of copper,lead and zinc metallic ores.However,due to the restriction of many factors for a long time,the basic geology and mineral exploration in the study area are relatively low,and the research on the metallogenic geological conditions,metallogenic regularity and ore prediction is less,all of these affect the further prospecting in this area.On the basis of extensive data collection,this paper describes the stratigraphic framework,tectonic characteristics,magmatic activities and metamorphism of Wanheyong area in detail.By the study of basic geology,geophysics,geochemistry and remote sensing images in this area,the metallogenic geological conditions and mineralization regularities are preliminarily analyzed and summarized,and these are determined that the main ore-bearing strata are the lower Permian Yujiabeigou Formation and the upper Jurassic Manketou Obo Formation,NW-trending faults control the distribution of most small deposits and mineralization points in the area,the metallogenic period is mainly concentrated in Mesozoic,and the deposit type is mainly hydrothermal deposit.Considering strata,magma,structure and other metallogenic geological conditions,there are three metallogenic prospecting areas and four prospecting target areas delineated according to geophysical and geochemical anomalies and distribution characteristics of deposits,ore spots and mineralization characteristics.Among them,Jijiayingzi copper,lead and zinc prospecting target area and Yuejiayingzi lead and zinc prospecting target area have the most prospecting potential.
