摘要
Abstract
This paper made a comprehensive analysis of landsat 7 ETM+ remote sensing image of the Tongling mining camp to obtain spectral features, extracted iron stain and OH group alteration information using spectral ratio and principal component analysis, generated alteration anomaly image by color density slicing, which displays clearly the advantageous ore-forming areas in the mining camp. The extraction results were tested by comparing the interpretations with geological structures and known ore occurrences in the Tongling area. A total of 11 prospective ore-forming zones have been delimited: 3 class-A zones with remarkable alteration information showing great ore-forming potential; 4 class-B with moderate alteration information and a reduced potential; and 4 class-C with dispersed alteration information and a little or possible potential.关键词
