Deformed areas, related to plate tectonics, experienced a complex and multiphase tectono-metamorphic evolution, challenging modern structural geology to develop new methods in order to unravel them. Such difficulties require fieldwork and geological mapping followed by careful laboratory work, where appropriate analytical technique(s) must be implemented according to the specific goal(s). This session calls on field-based structural studies at different scales involving the application of specific investigation methods in the lab, included but not limited to: microstructural analyses and kinematic reconstructions (e.g., optical, electronic, EBSD, cathodoluminescence), compositional and geochemical (bulk or in-situ) characterisations, P-T-D-t estimations, fluid inclusion, geochronological, and thermochronological analyses (e.g., LA-ICP-MS fission-track (U-Th)/He Ar-Ar). The appropriate integration of such methods allows the reconstruction of kinematic mechanisms and P-T-X conditions, through space and time, shedding new light on the long-lasting evolution of any ancient or recent geological context. We aim at fostering discussion on advances in field and laboratory applications, without forgetting the essential carefulness and the basic methods which must guide our approach in all phases of the job.
This session intends to stimulate an enthusiastic and lively debate. All contributions showing structural, petro-chronological, geo-thermochronological and/or geochemical inspections are greatly welcomed.
