Abstract

Uranius Patera, Ceraunius Tholus, and Uranius Tholus (three small constructs in the northeast Tharsis region) date to the Late Hesperian Epoch and define the earliest phases of constructional volcanism in the Tharsis province. All three volcanoes are interpreted as shields, built by effusive eruptions of low-viscosity lavas, presumably basalt. Ceraunius Tholus and Uranius Tholus also record pyroclastic volcanism in the form of mantling deposits on their flanks; Uranius Patera either did not experience pyroclastic volcanism or the deposits were subsequently buried by later effusive eruptions. Troughs observed on the flanks of Ceraunius Tholus and Uranius Tholus are interpreted to have been formed by fluvial surface runoff. These constructs are coeval with other small edifices in western Tharsis province and are coeval with plains volcanism in the southern Tharsis, Syria, and Sinai regions. ?? 2000 Academic Press.
