The course is highly practical consisting in 6 – 7 days of field work on Martian analogues environments in Spain or Morocco. During the field work the student will describe aeolian deposits, the sedimentary structures, the internal and external geometries of the sedimentary bodies, the stratigraphic relationships , sedimentary surfaces, subsurface and related processes. Then, the student will identify the possible similarities and differences with sedimentary bodies on Mars.
