Albor Tholus - NASA Mars Exploration PDF THEMIS characterization of the MER Gusev crater landing site Over the last ~2 years in Gusev Crater, the Mars Exploration Rover Spirit has observed coherent variations in mineralogy and geochemistry along an almost circular traverse of Home Plate, an 80 m-diameter outcrop of layered, basaltic tephra. (Co3)(2-) The crater statistics show about the same age for the floors of Ma'adim Vallis and Gusev crater, thus constraining the age of the last sedimentation event.Cabrol and colleagues use these statistics to confirm the idea that Gusev was a natural ponding zone and collector basin for Ma'adim Vallis sediment, which could be hundreds of meters thick.
