Continental crust preserves complex and often overprinted histories of deformation, magmatism, metamorphism, burial and exhumation. These histories are encoded in rock fabrics at scales ranging from mineral lattices to orogenic belts, yet the ways in which rock fabrics record different deformation processes or stages is rarely straightforward.
This session explores how structural, mineral, and magnetic fabrics can be integrated to reconstruct deformation kinematics and tectonic histories. We invite studies of igneous, metamorphic and sedimentary rocks from active and ancient orogens, using approaches including field-based structural analysis, crystallographic and microstructural fabric characterization, anisotropy of magnetic susceptibility and remanence, paleomagnetism, petrology, geochronology, seismic anisotropy, and analogue or numerical modelling. We particularly welcome contributions that combine or integrate independent proxies and methods; connecting mineral-scale and outcrop-scale observations to crustal-scale processes; or confront ambiguities caused by strain partitioning, magmatic versus tectonic fabrics, metamorphic overprinting and structural reactivation.
