Schroter's valley Rille in false color

This color-composite focuses on a section of Schroter's Valley (rille) and employs ultraviolet- to visible-color-ratio information to accentuate differences that are potentially diagnostic of ilmenite- (i.e, titanium oxide) bearing materials as well as pyroclastic glasses. Bluer units in these images suggest enrichment in opaque phases in a relative sense.
