Tharsis' Stage 2 (centered over the central section of the Valles Marineris) and Stage 3 volcanotectonic activity (in which tectonic activity became radially centered over the northwestern portion of Syria Planum), significant volcanic activity is understood to have infilled this basin, forming the modern plains terrains observed in the modern period. The burial of this putative drainage basin has been proposed as a source of the catastrophic floodwaters that are hypothesized to have formed the circum-

Some authors have suggested that the
Thaumasia Plateau was once a large, ancient drainage basin pre-dating the extensive volcanic formation of the Tharsis Rise. At this time, it was likely bounded by the same structures (the Claritas Rise to the west, the Thaumasia highlands to the south, and the

Thaumasia Planum and against the Coprates Rise, these sheet lavas were observed to onlap underlying plains materials and their associated ridged morphologies. Further volcanism occurred to the south of the Thaumasia highlands in

Alternatively, this heat may be supplied by magmatic intrusions that underlie rifts, or by magmatic piping supplying volcanic surface activity. Intrusive activity of this sort has been proposed to have sourced the
