Materials suspected of having a relatively felsic spectral character were identified in THEMIS infrared data of Eos Chasma by Hamilton and Christensen [1]. A survey of decorrelation stretched THEMIS infrared images over Eos and Ganges Chasmata reveals that similar materials are widespread throughout the region, but do not form large outcrops; rather they most commonly are associated with small knobs in the vicinity of olivine-rich materials. Ratios of THEMIS spectra from olivine-rich materials to Eos Chasma floor materials show an expected long wavelength absorption characteristic of olivine enrichment. Spectral ratios of the newly identified material to the floor materials, on the other hand, show an unusual shape dominated by a short wavelength absorption characteristic of felsic minerals, although this assignment is tentative. We are analyzing THEMIS and TES atmosphere-subtracted surface spectra to determine the phase(s) responsible for the observed signatures. This presentation will describe the mineralogy, morphology and thermophysical properties of these materials as observed by THEMIS and TES, as well as related characteristics observed in MOC and MOLA data.
