Geological map of the Echus Chasma region (Mars) by using HRSC (MEX) data .

The aim of this work is to realize a preliminary geological map of the Echus Chasma region of Mars (Fig. 1) to better understand the geological history of the area. The mapping work was performed using the HRSC data and other high-resolution images from previous Martian missions. The detailed mapping allowed to distinguish different geological and geomorphological units and to hypothesize the temporal succession of the principal geologic events that have characterized the region of Echus Chasma.
