Abstract: [1] A unique spectral component has been identified near and on the central peaks of two 30 km diameter craters in northern Syrtis Major. These exposures are clearly visible in Thermal Emission Imaging System (THEMIS) color radiance images as well as THEMIS and Thermal Emission Spectrometer (TES) surface emissivity data. Both TES and THEMIS data indicate the presence of increased 1050-1250 cm À1 ($8-9.5 mm) absorption compared to the surrounding basaltic plains, and TES data also display other absorptions at …
