Noctis Labyrinthus, Perspective View

December 4, 2007

This image was taken by the High-Resolution Stereo Camera (HRSC), onboard ESA's Mars Express imaged the Noctis Labyrinthus region, the ‘Labyrinth of the Night' on Mars.

The HRSC took these pictures on 25 June 2006 in orbit 3155, with a ground resolution of approximately 16 m/pixel.

This perspective view has been calculated from the digital terrain model derived from the stereo channels.

The region is located directly on the western edge of Valles Marineris, the ‘Grand Canyon' of Mars. The closely-spaced, deeply incised, smaller, labyrinth-like fractures are eye-catching.

Noctis Labyrinthus forms part of a complex graben-system. This system formed due to extensional tectonics. During the process, intense volcanism in the Tharsis region led to the formation of a bulge, resulting in tectonic stress. This caused the crust to thin out and form graben structures, which are elongated, trench-like features bounded by parallel normal faults. As one can clearly see in the context map, the upper portion of the martian crust in this area is largely fractured.
