摘      要：Hydrocarbon microseepage can result in related near-surface mineral *** this study,we evaluated the potential of detecting these alterations with field measured and satellite acquired hyperspectral *** soil samples and reflectance spectra were collected in the Xifeng Oilfield,a loess covered *** samples were analyzed in the laboratory for calcite,dolomite,kaolinite,illite,and mixedlayer illite/smectite content,and we processed reflectance spectra for continuum removal to derive clay and carbonate mineral absorption depth(H).High correlation between absorption depth and mineral content was shown for clay and mineral carbonate with field measured *** on the result for the field spectra,we proposed and tested a fast index based on the absorption depth of clay and carbonate minerals with a hyperspectral image of the *** detected hydrocarbon microseepage anomalies matched well with those shown in the geological map.
