Thermochronology studies carried out in crystalline rocks on the South America passive margin reveal distinct cooling patterns along coast. While most of presents syn-to post-rift final exhumation, region between parallels 29° and 35° S primarily pre-rift exhumation. This stretch coast corresponds to Uruguay southern Brazil, where Rio de La Plata Craton Dom Feliciano Belt occur. Previous area s...

Abstract. Subduction and exhumation are key processes in the formation of orogenic systems across world, for example, European Alps. For geophysical investigations these orogens, it is essential to understand petrophysical properties rocks involved. These result a complex interaction mineral composition rock fabric including textures (i.e., crystallographic preferred orientations). In this stud...

Collisional shortening in the external Western Alps was first accommodated by internal (distributed) deformation External Crystalline Massifs (ECM) and then on frontal crustal ramps (localized deformation). However, timing of transition between these two periods is still under-constrained, mainly because available dataset incomplete Alps. We here provide new zircon apatite fission-track (ZFT AF...

Seafloor spreading at slow rates can be accommodated on large-offset oceanic detachment faults (ODFs), that exhume lower crustal and mantle rocks in footwall domes termed core complexes (OCCs). Footwall experience large rotation during exhumation, yet important aspects of the kinematics—particularly relative roles solid-block flexure—are not clearly understood. Using a high-resolution numerical...

The long-term Pressure-Temperature-time-deformation ( P-T-t-d ) evolution of the internal zones orogens results from complex interactions between subducting lithosphere, overriding plate and intervening asthenosphere. 2-D numerical models successfully reproduce natural P-T-t - d paths, but most are non-cylindrical situation is far more due to 3-D pre-orogenic inheritance subduction dynamics. Me...

The development of regional metamorphism in areas of thickened continental crust is investigated in terms of the major controls on regional-scale thermal regimes. These are: the total radiogenic heat supply within the thickened crust, the supply of heat from the mantle, the thermal conductivity of the medium and the length and time scales of erosion of the continental crust. The orogenic episod...
