ASTER has higher spatial resolution in the VNIR region and higher spectral resolution in the shortwave infrared (SWIR) region in comparison with ETM+, which provide us an opportunity to distinguish various clay-alteration minerals accurately. In this paper, the 14 bands of ASTER were adopted to identify the lithologic and hydrothermal alteration minerals, such as the calcite, kaolinite and OH bearing...
In this paper, short-wave infrared reflectance(SWIR) standard data of Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) was utilized to extract information of red clay and siliceous limestone in Hongqipo gold fields, southwest of Guizhou, China. Based on the field-measured reflectance data of red clay and siliceous limestone in the mining areas, we calculated the coefficients...
