TheUranius group of volcanoes is located on planet Mars in the northeast part ofTharsis and includesUranius Mons,Ceraunius Tholus, andUranius Tholus. Along with theTharsis Montes to the southwest, they form part of a linear chain of volcanoes in theTharsis region.
They are dated to the LateHesperian Epoch and are part of earliest phases of volcanism in the Tharsis province. All three volcanoes are interpreted as basaltic shields. The volcanoes of the Uranius group were active for short periods of time (10 000–100 000 years) and are significantly older than the major Tharsis volcanoes.[1]
