Remote Sensing Geological Analysis And Prospecting Prediction Of Mangxi In Shangzhou District,Shaanxi Province

The research area is located at the mangling ridge mountains of south side of the eastern of Qinling Mountains,and is located in the west of the mangxi ridge of rock mass.It is the zhongshan mountain landscape.The study area is steep and deep cut,with the development of vegetation,and the traffic in some areas is inconvenient.The research area is located in Shaanxi-Henan and molybdenum,lead-zinc and polymetallic metallogenic belt.The research area has been found Polymetallic deposits of molybdenum,copper and lead zinc around the research area and the potential of metallogenic potential is good.In the satellite image of the research area,the small ring structure and fracture structure closely related to the distribution of mineral resources are extremely developed,and the former part corresponds to the known rock mass,reflecting the intrusion characteristics of the magma at the bottom.The latter extends in a disjointed direction,reflecting the complex structural deformation characteristics of the region.In order to be able to carry out prospecting and prospecting work in the research area more effectively,and obtain the information of remote sensing and prospecting information.The author carried out the study of remote sensing geological synthesis in the research area.This study explains and extracts the geological structure,stratigraphic lithology and mineralized alteration information of the region through remote sensing technology.The analysis and research have been used to determine the favorable prediction area for remote sensing prospecting,which provides a favorable basis and reference for further geological prospecting work in this area.In this paper,the data of KOMPSAT-2?ASTER and ETM are the main sources of information,combining with existing geological,mineral,geophysical and other information.We interpret in detail the stratigraphic?construction and intrusion of the research area.And we analysis the combination characteristics of the typical linear structure block structure and its relation to minerals.According to the ASTER data,three kinds of abnormal alteration information of the iron-stained?Al hydroxy?Mg hydroxy were extracted by principal component analysis,with directing at the characteristics of mineralized alteration type.Based on the above,this paper summarizes the distribution characteristics of all kinds of abnormal information and its possible causes and its relationship with minerals.Finally,through comprehensive analysis and evaluation,the information of remote sensing information in this area is summarized.After the comparative optimization,three areas were selected for the favorable prediction area:YC-1 LongWangMiao-NanTai forecast area ? YC-2 TaoGuanPing-JiTouShan forecast area?YC-3 The North of XiHe forecast area.After the later engineering verfication,it shows that the YC-1?YC-3 prediction area has great potential for prospecting and the target area for the next step.In this paper,a detailed study of remote sensing geological analysis is carried out the prediction region and plays an important indication of the geological prospecting work in the later stage.The research methods and results of this paper have some reference significance for geological exploration and prospecting in qinling area.
