- Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data were used to interpret hydrocarbon-induced clay and carbonate minerals in northwestern Songliao Basin, northeast China. Principal component analysis (PCA), band ratioing, and density slicing were adopted to distinguish the goal area of clay and carbonate minerals. Four principal components showed outstanding spectral response of hydrocarbon-induced clay and carbonate minerals: 5689-PC2 (the second principal component of input bands 5689), 1589-PC3, 1689-PC3 and 1348-PC. Then, density slicing was used to highlight the pixels with the largest DN (digital number) of PC images as the area of clay and carbonate minerals.The result suggests that hydrocarbon microseepage-induced mineral assemblage is related closely to the surface sediments. Compared with the anomalous area of ETM+ data, the distinguished area from ASTER datahas almost the same distribution, but more widely.
