Introduction: Crustal plateaus are a major class of tectonic features on Venus surface, and its study is essential in order to understand the geological evolution previous to the global resurfacing process. These regional units are flat topped highlands formed by tessera terrain, characterized by superposition of crosscutting structures [1-2], with complex tectonic patterns; also intratessera v...

Introduction: An understanding of the spatial and azimuthal distribution of lobate scarps on Mercury is important in constraining thermal history models and models for the origin of tectonic stresses [see 1]. Existing models involve either global (radial) contraction due to secular cooling of the interior, tidal despinning, or a combination of the two [1, 2, 3, 4, 5]. A comprehensive database o...

The notorious ~60° bend separating the Hawaiian and Emperor chains marked a prominent change in the motion of the Pacific plate at ~47 Ma (million years ago), but the origin of that change remains an outstanding controversy that bears on the nature of major plate reorganizations. Lesser known but equally significant is a conundrum posed by the pre-bend (~80 to 47 Ma) motion of the Pacific plate...

Mid-ocean ridges, transform faults, subduction and continental collisions form the conventional theory of plate tectonics to explain non-rigid behaviour at plate boundaries. However, the theory does not explain directly the processes involved in intraplate deformation and seismicity. Recently, damage structures in the lithosphere have been linked to the origin of plate tectonics. Despite seismo...

the magnesite veins are located in the beni bousera massif (internal rif, morocco), especially in tafidest region about 103 km sw of the tetouan city. they are hosted by perridotite and serpentinite formations.  the aim of this study is to clarify the origin of this type of orre genesis. geochimical study of magnesite ore reveals that is a cryptocrystalline magnesite, formed by the co2-rich hyd...

[1] The south polar terrain (SPT) of Saturn’s moon Enceladus is a mysteriously active region that exhibits intriguing tectonic signatures and widespread fracturing. The central region of the nearly-circular SPT is depressed into the surface by a few hundred meters and bounded by a ring of cliffs roughly 1 km high. In this study, we investigate whether this depression and surrounding mountainous...
