Extraction of remote sensing alteration anomalies of three types of ore deposits and its application
三种不同类型矿床分类型蚀变遥感异常提取及其应用

Application of remote sensing alteration anomalies has made great progress in survey of mineral resources and a number of ore occurence have found by using of remote sensing technology. However, the range of anomalies given this approach was too bigger and it was not specific. In general, the similar deposits had the similar types of the characteristics of the spectrum of their altered rocks. If these characteristics of the deposits were used in extraction of remote sensing alteration anomalies to limit range of anomalies by the spectrum characteristics of altered rocks of deposits, remote sensing alteration anomalies could be extracted with having special target in order to identify remote sensing alteration anomalies of different types of deposits. This approach was used in the East Tianshan region and the East Junggar region with very good results and a number of ore occurence have been found.
