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."
Many spacecraft have found a large number of layers exposed in craters, canyons, and various depressions. Noctis Labyrinthus displays many layers both in its walls and on floor deposits. layers can be formed in many ways such as volcanic flows, volcanic eruptions, wind blown dust, and under bodies of water. Layers that break up into large boulders or blocks are thought to be formed from the hard rock like basalt from the many volcanoes on the planet. In many places, however, the layers are seen to consist of fine particles. The wind often carries these small particles away in time. The fine particles are interesting, they could be made of clay which requires water for its formation. Indeed, spectroscopes onboard orbiting spacecraft like the Mars Reconnaissance orbiter have detected clay in some of the layers.
The idea that layers in Noctis Labyrinthus contain clay is exciting. It implies lots of water in the past. Life may have originated when some of these layers were put down. The water may have been under a lake, but it also may have come from the ground.
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.
