Trouvelot Crater Deposit October 9, 2009 Like many of the
craters in the Oxia Palus region of Mars, Trouvelot Crater hosts
an eroded, light-toned, sedimentary deposit on its floor.
Compared with the much larger example in Becquerel Crater to the
NE, the Trouvelot deposit has been so eroded by the scouring
action of dark, wind-blown sand that very little of it remains.
This dark sand still remains in samll dunes.Tiny outliers of
bright material separated from the main mass attest to the once,
more areally extensive coverage by the deposit. A similar
observation can be made for White Rock, the best known example
of a bright, crater interior deposit. The origin of the
sediments in these deposits remains enigmatic but they are
likely the result of fallout from ash or dust carried by the
thin martian atmosphere. Topics: Hospitality Recreation,
