Reinterpretation of Tractus Fossae region as an asymmetric rift system on Mars
The Tractus Fossae region of Mars is a wide area dominated by grabens, normal faults and pit crater chains.

| Sumario: | The Tractus Fossae region of Mars is a wide area dominated by grabens, normal faults and pit crater chains. In this work, based on previous studies on the area and the new interpretation of topographic data and morphological units based on images as a geologic framework we present a new insight on the origin of the graben structures as well as on the processes associated with the formation of the volcanic features. Here we propose a new model for this region, on the basis of new measurements of graben extension and geological interpretations, together with a reinterpretation of the stratigraphy and the geologic history of the area. Finally, it is postulated that this region underwent a tectonic regime analog to an asymmetric rift system on Earth. © 2008 Elsevier Inc. All rights reserved. |
