Mars Society Switzerland
1 3 4On November 20th 2010, the Mars society Switzerland, in partnership with CHYN (Center of Hydrogeology and Geothermics, Neuchâtel University) organized a symposium on Martian geology in the frame of the 8th Geoscience Meeting (“8SGM”) which was hosted in University of Fribourg (Pérolles2), by the Department of Geosciences of the University of Fribourg and the Platform Geosciences of the Swiss Academy of sciences-SCNAT. See: We now know enough about this neighbor planet, to speak of it as a geologic object. Mars primordial history was shaped by water as well as lava. Water stayed liquid long enough in pools, lakes or even maybe oceans, to alter lava rocks into all kind of hydrated rocks, phyllosilicates, sulfates and even into carbonates, that we do find on Earth. When Mars internal dynamo stopped because the mantle and the core of the planet were too cold hence too stiff, the magnetosphere disappeared, most of the atmosphere escaped and water could not stay liquid on the surface. It was however saved as visible ice on the poles, as veils of stratospheric clouds of ice particles and as ice within the immediate sub-soil, even at medium latitudes. Since there have been no plate tectonics and very little erosion during the last 3.5 billion years, Mars, as our rocky sister planet, is an open book for Earth early history. The symposium covered the essential aspects of Mars Geology and Climate.
