Deep in the Hellas basin on Mars, wind has exhumed layered terrain showing ductile deformation. A kilometer-scale cellular pattern is identified, consistent with thermal and/or compositional (diapiric) convection. ‘Frozen-in’ convection within an impact melt sheet is consistent with observations, but overturn(s) within an evaporitic layer cannot be excluded. Spectrometer follow-up will be compl...

The structure of the southwestern branch Alpine orogen is affected by extensive Late Triassic evaporites. These evaporites have been involved in polyphased salt tectonics since early Liassic, coeval with Tethyan rifting, and are décollement level for thrusts external parts during orogeny. role this arc re-evaluated order to determine relative importance deformation related motion respect main c...

Carbon fluxes in subduction zones can be better constrained by including new estimates of carbon concentration in subducting mantle peridotites, consideration of carbonate solubility in aqueous fluid along subduction geotherms, and diapirism of carbon-bearing metasediments. Whereas previous studies concluded that about half the subducting carbon is returned to the convecting mantle, we find tha...

High-quality 3D seismic reflection and well data are used to investigate the distribution, evolution history significance of tectonic faulting in a salt minibasin offshore Espírito Santo, SE Brazil. Displacement-length (D max -L) plots, displacement-depth (D-Z) plots structural maps compiled understand growth distinct fault families. Interpreted structures include crestal, corridor, listric key...
