[1] Comparison of analogue experiments at crustal and lithospheric scale provides essential information concerning the mode of deformation during lithospheric extension. This study shows that during extension, lithospheric deformation is controlled by the development of shear zones in the ductile parts. At lithospheric scale, the global deformation is initiated by the rupture of the brittle man...

Introduction: Valles Marineris is the largest tectonic canyon in the solar system, with a length of ~2500 km, depths of up to 10 km, and widths in excess of 100 km. The location of this canyon on Tharsis, and its orientation radial to the center of the rise suggests Tharsis control of Valles Marineris tectonism. Tharsis loading dominated the tectonic history of Mars, accounting for the radial g...

Fluid circulation at fractured basement/cover unconformity is of first importance for geothermal energy exploitation especially in continental rifting as the Upper Rhine Graben. This unconformity presents lot of natural fractures which constitute a large permeable fracture network driving brine movement. That constitutes a reservoir of hot water, which is exploited by several geothermal power p...

The Mangala Valles is a 900-km long outflow channel system in the highlands adjacent to the southeastern flank of the Tharsis bulge. This work was intended to answer the following two questions unresolved in previous studies: (1) Was there only one source of water (Mangala Fossa at the valley head which is one of the Medusae Fossae troughs or graben) or were other sources also involved in the v...

We study the earthquake response of the Zevulun Valley basin, underlying northern Israel‘s largest urban area with two-dimensional viscoelastic seismic modeling of a detailed geological section. We found that amplification of the horizontal vibrations, the ratio of basin to no-basin response spectra, correlates with basin depth. In the deepest portion of the basin (Qishon graben) long periods (...

The relative timing between crustal extension and salt deposition can vary spatially along passive margin basins as continents unzip, or the locus of shifts toward embryonic ocean spreading center. Determining deposition, rifting, seafloor is often problematic due to diachronous nature ability fill pre-existing topography, subsequent flow deformation that salt. We here use 2D PSDM seismic data ...
