This paper presents a study of the structural lineaments of the Pantanal extracted visually from satellite images (CBERS-2B satellite, Wide Field Imager sensor, a free image available in INTERNET) and a comparison with the structural lineaments of Precambrian and Paleozoic rocks surrounding the Cenozoic Pantanal Basin. Using a free software for satellite image analysis, the photointerpretation ...
Breccias associated with tectonic, fluid and sedimentary evolution of rifted margins can provide information on a variety processes reflecting the modes extension. In this paper, we analyse numerous breccias exposed in Agly Massif that was part European side Cretaceous rift now inverted eastern Pyrenees. Using combination petrologic sedimentologic analyses, field-based structural study, multiva...

[1] Paleomagnetic data from the Internal Sierras unravel the kinematic relationship between basement (Guarga, Gavarnie, Bielsa) and cover thrusts (LarraMonte Perdido). The new data come from an area of 100 km along strike and 5–15 km across strike of the southwestern Pyrenees. The area covers a variety of structural positions that range from cover to basement thrusts. From 84 sites located in U...
The timings of the onset oceanic spreading, subduction and collision are crucial in plate reconstructions, but not always straightforward to resolve. Paleo-Tethys evolution dominated Paleozoic-Early Mesozoic tectonics West Asia, timeline events is still poorly constrained. We present new detrital zircon ages from Binalud Mountains NE Iran, order determine timing tectonic region, wider implicati...
Abstract Subsidence and uplift patterns thermal history of sedimentary basins are controlled by tectonics, mantle dynamics surface processes, such as erosion, sediment transport deposition their links to climatic variations. We use combined thermo-mechanical stratigraphic numerical modelling techniques quantify the between tectonic processes. aim assess evolution subsidence rates asymmetric ext...
Abstract We make use of own geological mapping, interpretations seismic reflection profiles and deep geophysical data to build a lithospheric-scale cross-section across the European Western Southern Alps (Varese area) model progressive restoration from end Mesozoic rifting present-day. Early phases Alpine orogeny were characterized by Europe-directed thrusting, whereas post-Oligocene shortening...
Abstract In the central Southern Alps (N Italy) some well-preserved Permian extensional structures, that exceptionally escaped Alpine deformation, have been recently identified. Their analysis offers important insights for interpretation of post-Variscan tectonics affecting during Permian. We describe here a previously unknown fault system related to development Early Orobic Basin, where large ...
Plate tectonics is one of the major factors affecting the potential habitability of a terrestrial planet. The physics of plate tectonics is, however, still far from being complete, leading to considerable uncertainty when discussing planetary habitability. Here, I summarize recent developments on the evolution of plate tectonics on Earth, which suggest a radically new view on Earth dynamics: co...
