Eos Chasma is achasma in the southern part of theValles Marineris canyon system of theCoprates quadrangle and theMargaritifer Sinus quadrangles of the planetMars.
Eos Chasma’s western floor is mainly composed of an etched massive material composed of either volcanic or eolian deposits later eroded by the Martian wind. The eastern end of the Eos chasma has a large area of streamlined bars and longitudinal striations. This is interpreted to be stream-carved plateau deposits and material transported and deposited by flowing fluid.Ganges Chasma is an offshoot of Eos Chasma.MRO discovered sulfate, hydrated sulfate, and iron oxides in Eos Chasma.[1]
According to an analysis by Vicky Hamilton of theUniversity of Hawaii, Eos Chasma may be the source of theALH84001 meteorite, which some believe to be evidence of pastlife on Mars.[2][3]However, the analysis was not conclusive, in part because it was limited to parts of Mars not obscured by dust.
