Study On The Geological Conditions Of Mineralization And Prospecting Direction In Xiyingpan-Jishengtai Of Inner Mongolia

Inner Mongolia Xiyingpan-Jishengtai area is located in the middle of InnerMongolia,which in the middle of the Daqingshan Mountain of the middle of the Yinshan mountains.Study aera is located in the northern margin of the North China Platform,and is part of the Yinshan-Daqing Mountain's east-west extrusion belt,which is in Yinshan iron,copper,lead,zinc,gold and other polymetallic Mineralization zone.In the study area,tectonic development and magmatic activity are strong,which are favorable locations for forming polymetallic minerals such as copper,nickel and gold,and have good geological and mineralization background.Based on the data of regional geological background,through the field geological work,this paper studies the geological conditions such as fromation,magmatic rock and tectonics,and analyzes the ore-controlling and metallogenic regularity effect of formation,magmatic rock,tectonics,and establishes the metallogenic model.Combing the geophysical and geochemical and remote sensing are discussed.The mineralization area and metallogenic belt in the study area are pointed out.Which has some guiding significance to the periphery and deep prospecting in the area.At the same time,it has certain theoretical and practical significance for the exploration of regional mineral resources,and has achieved the main understanding and achievements as follows:1.Based on the study of the regional geological background,through the field geological survey,it is considered that the rock assemblage in the study area is mainly a set of Neolithic shallow seashore sedimentary Bayan Obo group rocks,in which the crystalline limestone in the Halahuogete group,Slate are hot and liquid alteration type copper,nickel and other metal ore body of the main storage layer.2.The granite rocks exposed in the study area are mainly Permian monzonitic granites and Carboniferous gabbro,and the morphology,scale,main mineral composition,structure and rock type of magmatic rocks are identified.Among them,It is the most closely related lithofacies and Cu,Zn,Ni and other minerals.3.By analyzing the characteristics of the NE-trending and NW-trending faults in the studythe fractures of the north-east Hulitai-Daerbugai,the Changheishan fault and the north-west Huanghuatan-Jishengtai fault are analyzed.In the north-east anorth-west fault distributes deposits(points).And the distribution of minerals in the study area is related to the north-east and north-west faults.4.Based on the analysis of metallogenic geologic conditions and typical deposits in the study area,it is concluded that the northeast,northwest fault,gabbro and Halahuogete formation' crystalline limestone,slate are the main ore controlling factors in the study area.The ore-forming time is mainly concentrated Paleozoic mineralization period,and the initial establishment of mineralization model.The geophysics,geochemistry and remote sensing data of the study area are analyzed synthetically,and the-Xiaonanshan-Jishengtai ore belt and Hulitai-Daerbugai ore belt are pointed out.
