This observation targets a spectrally-diverse massif in Terra Sabaea. There are at least four potential spectral units here, indicating olivine and silica-rich surfaces as well as altered minerals. This massif may represent a crustal block excavated during the Hellas Basin impact. If so, the spectrally-diverse nature of this massif may provide some insight into the rock variability of the deep crust under the impact site.
