About this image

This image shows two representations of the same infrared image covering an area near Mare Cimmerium. On the left is a grayscale image showing surface temperature, and on the right is a false-color composite made from 3 individual THEMIS bands. The false-color image is colorized using a technique called decorrelation stretch (DCS), which emphasizes the spectral differences between the bands to highlight compositional variations.
This area contains a mixture of basaltic materials (magenta/purple) and dust (green/blue). Faint blue areas may be due to some thin water ice clouds. The different compositional units are sometimes correlated with crater floors and other surface features, but they are often not tied to valleys, lava flows, etc... indicating that the surface materials could be mobile (dust and sand).
