Amazonian geologic history of the Echus Chasma and Kasei Valles system on Mars: New data and interpretations
International audience New high-resolution datasets have prompted a mapping-based study of the 2500-km-long Echus Chasma and Kasei Valles system that utilizes geomorphic details, stratigraphic relations, and cratering statistics derived from the new datasets. Our results suggest that between the Hes...
