Remote sensing survey of the mineralogy of Valles Marineris: Insights into magmatic and sedimentary processes on Mars
Intervenant : Jessica Flahaut
The last decade of Mars exploration has produced vast and under-exploited datasets on the physical and chemical properties of Mars crust that raise questions about a number of paradigms pertaining to the first hundreds of millions of year of planetary evolution. The present talk makes use of recent high resolution remote sensing imagery to study ancient igneous rocks, exposed dikes and sulfate-rich sediments that are all observed in the giant (4000 km long, 10 km deep!) canyon system of Valles Marineris, and bring clues about Mars early history.
