Noctis Labyrinthus
Noctis Labyrinthus is a group of intersecting canyons that lies at the western end of Valles Marineris. It is in the Phoenicis Laus quadrangle. The center coordinates of Noctis Labyrinthus are 7.0 S and 102.2 W. The canyons of this feature are faults known as grabens. Grabens happen when a center section drops lower than sections on either side.
Discovered by Mariner 9, the name "Noctis Labyrinthus," means "the labyrinth of the night."
Research from 2009 found a variety of minerals, including clays, sulfates, and hydrated silicas, in some of the layers.[1] These minerals are associated with water. The water may have been from a body of water or may have come from groundwater. Since water had to be involved in their formation, evidence of ancient or existing life may be found there.
