| Abstract: | The methodology of "interference suppression-principal component analysis-exception filter" is applied in the geological survey in Ar Horqin Qi, Inner Mongolia. The alteration anomaly information is extracted by remote sensing on the basis of metallogenic condition in the study area and characteristics of Landsat 8 OLI sensor data. Quite a few mineralized occurrences are also discovered in the field validation for the extracted result, which provides strong support for geological prospecting. |
