Geochemical Characteristics And Prospecting Significance Of Magmatic Rock In Baogedewula Region Of Inner Mongolia

Located in the southwest of The Derbugan deep fracture,Baogedewula in the InnerMongolia is the transitional crustal structure zone between the Siberia platform and theNorth China Platform.In this area where the faults develop magmatic activity duringYanshanian is strong,forming a large number of intrusive rock and volcano rock.Along withthe magmatic activity,the study area (secondary quartz rocks)has developed the strongsilicification、greisenization、potassium、limonite alteration、 epidotization、chloritization、iron and manganese。Copper lead、zinc、silver、 gold、tin、tungsten、molybdenum andother metal mineralization phenomenon in the district is obvious and is one of the mostimportant polymetallic metallogenic belt in China.From2008to2011, Shijiazhuang University Of Economics take the project in thisarea named"Integrated exploration for silver polymetallic mineral in the Baogedewula ofXinbaerhuyouqi in inner Mongolia".This project has completed the geochemical mapping、geophysical surveying、geochemical、 prospecting, trenching、drilling and so on. Thegeological tectonic background, geochemical and geophysical characteristics ofBaogedewula were found out preliminarily.In Baogedewula area we has put forward threefurther work mineral area, Nuwentingtunshigele silver mining, Hanggaiyinhundi miningand Laerzhatinghundi mining.Ring unearthed anomaly and IP anomaly detection of soil.Inrecent years, we received a large number of field data and determined the prospectingdirection preliminarily。This paper is based on the " Integrated exploration for silver polymetallic mineral inthe Baogedewula of Xinbaerhuyouqi in inner Mongolia", the author based on the field work,carry out the depth research work to the geologic characteristics, magmatic rocks,geochemical characteristics.The specific work in the research area consisted of1:1millionsoil geochemical survey, comprehensive geophysical profile measurement, trenching anddrilling.The sampling chemical analysis test in this area included major elements, traceelements, rare earth elements, bedrock spectrum of themagmatic rocks。The main results of this paper are as follows:①Introduces the geologicalcharacteristics of magmatic rocks in the study area.②Throught the rock geochemicaltesting of magmatic rocks in the study area (major elements, trace elements, rare earthelements)the source and magma evolution characteristics in the region aregained.③throught1:1million soil geochemistry measurement and comprehensivegeophysical profile work We get the abnormal area in the study area, where we carry outgeophysical prospecting, drilling and trenching to summarize the relationship betweenmainly mineralized bodies(ore body) and magmatic rocks.All the inclutions provideguidance for the further prospecting work.
