Sirenum Fossae - False Color

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of Sirenum Fossae. The linear depressions at the top of the image are called graben. Graben are created in regions of extensional tectonic stress, where the bedrock is faulted and pulled apart, allowing linear sections of the surface to drop downward along paired faults. The Sirenum Fossae graben are 2735km (1700 miles) long.
