Simulation of the capabilities of an orbiter for monitoring the entry of interplanetary matter into the terrestrial atmosphere

3 octobre 2014

In comparison with existing ground-based camera networks for meteors monitoring, a space-based optical system would escape dependency on weather and atmospheric conditions and would offer a wide spatial coverage and an unrestricted and extinction-free spectral domain. The potential rates of (...)

Age dates of valley network drainage basins and subbasins within Sabae and Arabia Terrae, Mars

3 octobre 2014

The precise timing of valley network drainage basin formation is critical to understanding the history of water and climate on Mars. To determine whether there are any variations in ages within separate drainage basins and subbasins that may reflect local or regional variations in climate or (...)

Multi-scale analysis of water alteration on the rockslope stability framework

3 octobre 2014

Water is an important weathering factor on rock discontinuities and in rock mass mechanical behaviour because of its chemical features such as temperature, pH or salinity which make it a "good" candidate to rock degradation. Furthermore the increase of rainfall frequency or intensity highlights (...)

Vertical movements along the northern border of the West African Craton : the Reguibat Shield and adjacent basins

17 septembre 2014

The absence of a sedimentary record on large cratonic areas often prevents the reconstruction of the history of their vertical movements. The Reguibat Rise, belonging to the West African Craton, is typically a large basement high, whose Meso-Cenozoic history is poorly known because of the (...)

Reconstruction of low temperature (<100°C) burial in sedimentary basins: A comparison of geothermometer in the intracontinental Paris Basin

28 août 2014

The thermal evolution of sediments in the shallowest part of sedimentary basins is challenging to investigate as most of the geothermometers are at their application limits. This is typically the case of the Callovian-Oxfordian claystones at the eastern border of the Paris Basin. A recent 2000m (...)
