Noctis Labyrinthus, Perspective View
This image was taken by the High-Resolution Stereo Camera (HRSC), onboard ESA's Mars Express imaged the Noctis Labyrinthus region, the â€˜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 â€˜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.
