Landscape features in Trouvelot Crater and its surroundings
In the highlands of Arabia Terra, where Trouvelot Crater is located (right half of the image), interesting geological phenomena can be observed. Notable are the extensive dark deposits, which consist of sands from crushed volcanic deposits and ash that the wind has piled into large dune fields ('barchan', or crescent-shaped dunes). A heavily eroded crater rim indicates that the impact creating this crater must have occurred earlier than the Trouvelot impact. This is also evident from the fact that Trouvelot's crater rim is much more pronounced and sharp-edged. Rock masses that have slid down from here form extensive terraces (terraced wall) above the floor. Particularly striking are the bright sediments that have accumulated in a 20-kilometre-long and 270-metre-high hill in the middle of the crater (light-toned mound).
