Abstract The Qinling Orogen, located between the North and South China Blocks, records subduction-collisional orogeny along Paleozoic Shangdan Triassic Mianlue sutures, Mesozoic intracontinental orogenesis, which all played an important role in building present tectonic framework topography. strike-slip Shagou ductile shear zone that overprints suture Belts is crucial for understanding deformat...

The geological record of deep fossil seismogenesis in subduction zones is limited due to common rock overprinting during exhumation and only a few regions expose well-preserved deeply exhumed structures. We investigated mesoscopic contractional duplex formed at blueschist facies conditions continental metasediments the Northern Apennines (Italy). Field observations reveal strain partitioning wi...

Abstract Orogenic gold deposits, though construed to focused fluid flow during orogenesis, commonly post-date the main accretionary events. Several lines of evidence indicate that orogenic formation in Arabian–Nubian Shield continued through orogen collapse stage and associated rapid exhumation thermal re-equilibration. The Gidami deposit Eastern Desert Egypt is with post-foliation, brittle-duc...

We discuss the important role of tangential stretching in Central Alps highlighting that are a truly three-dimensional orogen. A review pressure-temperature (P-T) conditions allows us to define three major breaks metamorphic pressure (P-breaks) across nappe pile. constrain kinematics mylonites associated with these P-breaks and report eight new RbSr multi-mineral isochrons age mylonites. Kinema...

The Southwest Indian Ridge (SWIR) at 9^168E and 52^538S is characterized by ultra-slow, oblique spreading and contains one of the few documented occurrences of pyroxenite veins associated with abyssal peridotites. The origin of these uncommon lithologies is still debated.We present a detailed study (including electron microprobe and laser ablation inductively coupled plasma mass spectrometry) o...

Post-orogenic extension in back-arc regions is classically associated with metamorphic core complexes (MCCs) cored exhumed rocks and granitic intrusions interacting low-angle detachments. When additional heat provided by the advected asthenosphere below extending region, for instance above slab tears, high-temperature migmatite-cored domes composite are emplaced whose geometry kinematics of emp...
