1:50 000 Regional Geological Mapping In Ha La Qiao La Regional, Xin Jiang

1:50 000 geological mapping is the most important work of the basic geology.Our country is very large,so the work is rough and vastness.The stratagem aim of the regional geological survey in twenty century bring forward in the last in 80s.Apparently,it is not dissymmetry with our large country and the new geolory ore-searching.However,the Remote Sensing Technology has a great development in the last year.Has being used in 1:50.000 regional geological survey.Ensure the aim come be true.The research based on the item of the 1:50 000 regional geological mapping in ha la qiao la regional,xin jiang.Try to make remote sensing technique using in 1:50 000 remote sensing geological mapping.Making the remote sensing geological mapping accept by al of the geological operator.So as to shorten the geological mapping cycle,reduce the geological mapping work intensity.decrease the geological mapping devotion,enhance the geological mapping quality,rich geological mapping production.At the 1:50 000 remote sensing geological mapping in ha la qiao la regional,xin jiang.Use the ETM+ as the mapping date of remote sensing,use the method of principal component analysis,ration analysis,HIS transform and so on to enhance and extraction image information,also to enhance the interpretation of the image.To commix the image cell section method,field geological surveying date,1:200 000 geological mapping production,via manpower visual interpretation to compartmentalize geological boundary.Protracted the Geological Map.In this mapping.We based on remote sensing images processing.field geological surveying and remote sensing interpretation.We correctted some deficiency of the 1:200 000 geological mapping.Making the geological boundary.structure and fault more impersonality,nicety.Did the remote sensing Geological Map.Simultaneity,we extracted the alteration information.circled the farther prospecting targets,offered the farther orientation of the geologic prospecting.
