Mountain belts represent the lithospheric response to plate convergence, recording deformation and metamorphism through different spatial and temporal scales, with fluid circulation often enhancing positive feedback among orogenic processes. From shallow brittle deformation to ductile flow and metamorphism at deeper crustal conditions, orogens preserve complementary records of processes driving converging margin evolution in both oceanic and continental settings, which can be investigated through structural, metamorphic and temporal perspectives. Deciphering their complex history benefits from multidisciplinary approaches integrating field-based observations with analytical and modelling techniques. This session welcomes contributions that include field observations, petrological and geochemical characterisation, microstructural and kinematic analyses, geochronological and thermochronological constraints, P–T–t–D reconstructions, as well as numerical or analogue modelling applied to different crustal levels and scales. We aim to integrate shallow and deep perspectives, which together offer complementary constraints on the processes controlling the architecture and long-term evolution of mountain belts. In addition, regional contributions on accretionary and collisional orogens, fold-and-thrust belts, shear zones, foreland basins and orogenic wedges are welcome.
