In evaluating Concepcion, the main efforts will be in the Geomorphology (as stated above), plus a look-see for any evidence of the parent meteorite body. (There might also be an APXS exam of the sulfur-salt pavement fragments to see if composition is changing during the long traverse.)
One of the interesting aspects of this crater is the "disturbed" look of the nearby dunes. They seem to still bear the scars of the seismic shock and the impact of debris from the impact. It is reasonable to speculate that no major dune-moving wind event has occurred since this crater was formed. There is an implication that dune-moving high wind events only occur during a different climatic period than Mars is in now, perhaps only every few tens of thousands of years (due to variations in Mars' orbit and precession of its axis). About the only thing missing from the site (from immediately after the impact) is the very fine and light white sulfur dust from the fragmentation of the pavement. |
