Extraction Mechanism of Alteration Information on Finedisseminated-type Gold Deposits in Qian Gui Area
黔桂地区微细浸染型金矿蚀变信息提取机理

This paper studies the geochemical and spectral information on the"silification"."lemonitization"."clayization".and "carbonatization"related to finedesseminated-type gold deposits in Qian Gui area.Four content factors are extracted on the basis of researching the rock-orecomposition; three TM band reflectance ratio factors are extracted on the basis ofresearching the rock-ore spectral features, and the alteration information are extractedthrough correlation analysis and image processing.
