Comparative Lineament and Geomorphic Analysis of Chaotic Terrains and Noctis Labyrinthus, Mars
Abstract
dc:description.abstract<p>Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns are seen at both sites, where geometric topographic highs are bounded by low troughs. Lineaments, topography, and geomorphology of NL and chaotic terrains were analyzed to determine tectonics and fluid influence in the formation and evolution of both sites. NL shows preferential fracture patterns associated with regional extension. Lineaments within chaotic terrains do not show cumulative preferential trends but demonstrate irregular fracture networks associated with collapse structures. Theoretical models for the evolution of both systems were produced, developing a better understanding of processes that shaped the Martian landscape</p>
