Mareotis Fossae is a group of fossae (troughs) in the Arcadia quadrangle of Mars, located at 44° north latitude and 75.3° west longitude. It is about 1,860 km long and was named after an albedo feature at 32N, 96W.
eruptive style and has been likened to the basaltic plains volcanism seen in Idaho’s Snake River Plain. This category of volcanic activity is intermediate between flood (plateau) basalts and Hawaiian volcanism.
The region is transected by numerous northeast-trending grabens that form parts of the Tempe, Mareotis, and Tantalus Fossae; these are fracture systems of varying ages that are oriented radially from the Tharsis bulge. The region west of Enipeus Vallis is characterized by Hesperian-aged volcanic flows from Alba Mons. The area to the east consists
