Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Origin of the Bulge Topography Within Caloris Basin, Mercury
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

Abstract The formation of gullies on Mars has often been attributed to the melting of (sub)surface water ice. However, melting‐based hypotheses generally overlook key processes: (a) sublimation cooling by latent heat absorption, (b) the non‐stability of ice where melting conditions can be reached, and (c) the particular microclimates of gullied slopes.
