Dear colleagues, we would like to draw your attention to the session 3e "Integrating petrology, geochronology and geochemistry of subduction zones", organized under the umbrella of the upcoming Goldschmidt 2024 conference, to be held in Chicago from August 18 to August 23. The description is given below.The abstract submission deadline is March 29. Subduction zones are important locations for shaping the Earth's physical and chemical evolution. Processes of subduction zone metamorphism and fluid-mediated mass transfer between subducted lithosphere and overlying mantle wedge result in substantial changes of the properties of the subducting slab, including rheology, mineralogy and chemistry. Understanding the processes and changes in the slab due to subduction metamorphism impacts our understanding of geochemical cycling at subduction zones, the generation of arc volcanoes, the formation of continental crust, and the concentration of elements of economic importance. In this session we invite contributions focusing on studies of natural samples, as well as both experimental and theoretical approaches. We invite studies that use a range of techniques to address these questions, including petrology, thermobarometry, geochronology, novel stable isotope systems, trace elements, and thermodynamic modelling. We will be grateful for receiving topical abstracts which may bring our understanding of complex processes occurring during subduction and beyond to yet another level.
