The Application Of Remote Sensing Geological Interpretation And Mineralized Alteration Information

Rapid development of remote sensing technology in the late 20 th century,is one of the available resources and the environment information of efficient new technology,the combination of remote sensing and geology is currently one of the important subject of geology.Especially in the transportation inconveniences,the natural conditions in the poor areas of the prospecting work has a prominent advantage.Based on the new hundred Luke to the heap of Inner Mongolia as the study area,on the basis of the domestic high image and Aster image data,the geological interpretation of the study area and the alteration information extraction,comprehensive analysis and draw four metallogenic forecasting area,provides a more comprehensive prospecting in the study area prospecting information.The main results are as follows:1.Collect satellite remote sensing and geological mineral information of the research area,and carry out detailed research and classification analysis on relevant data.Analyze the metallogenic environment and metallogenic conditions in the area,select the domestic high score data as the data source,and conduct human-computer interaction interpretation,and finally obtain the lithology and structural features of the research area.The Aster data was selected as the data source and preprocessed to prepare for further alteration.2.The analysis and research area alteration mineral spectrum information,based on threshold method using PCA method and ratio method respectively on iron stain and hydroxyl abnormal information extraction,using the method of SAM to other alteration mineral extraction,the study area alteration extraction figure.3.The potential alteration zone of the study area was determined by the combination of rock spectrum and optical wafer,and the interference factors were excluded.4.To study the integrated geological and geochemical anomaly information,will eventually get all kinds of information into ArcGIS format,focus on analysis and summary,select the corresponding four prospecting prospect areas,to provide a significant role in the prospecting work in the study area.
