Abstract :
Uses multispectral short-wave-infrared (SWIR) and long-wave-infrared (LWIR) remote sensing to map mineralogy associated with hot springs and epithermal mineral deposits. Selected sites around the world covering a range of active/inactive hot springs and deposit types are being studied using the MODIS/ASTER airborne simulator (MASTER) and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). MASTER and ASTER data analysis contribute to mineral mapping in the VNIR/SWIR, however, their main contribution is improved mapping of siliceous sinter utilizing LWIR signatures. Integrated study using these VNIR/SWIR/LWIR remote sensing datasets is in progress.
