Abstract : The Cerberus lava plains on Mars, present various volcanic, fluviatil and tectonic morphologies. The observations of this region have been compiled in a geological map to detail the outflow and volcanic events. The Cerberus plains are dated between 250 millions years and now, and present complex stratigraphic contacts between the low volcano shields and the large lava flows. The lava volume has been estimated around 17.104 km3 from an original basin modelling. Two research axes have been developed from the mapping of the Cerberus plains: (1) The study of the volcanic aeolian deposits. The study of the low albedo area on Cerberus suggests it is a subsurface strata of volcanic sediments, like ashes or tephras, which has been exhumed by the formation of Grjota' Vallis, and distributed by the winds over the area. This low albedo area is a possible evidence of explosive activity in the cerberus plains. (2) The study of the effusive lava flows. The rheological properties of the Cerberus lava flows evidence two types of viscosity which are independent of the flow rates. The first viscosity values corresponds to the average vicosity values of other martian lava flows (105 Pa.s), and the second viscosity values are the lowest found on mars up to date (<103 Pa.s).
