Dear colleagues, We're writing to invite abstract submissions to our interdisciplinary AGU session V013: The Evolution of Igneous Systems as Revealed by Synchrotron and Microanalytical Methods. Abstracts are due Wednesday, August 3rd. Session description: Advanced high-resolution and high-sensitivity analytical techniques continue to reveal new insights into the evolution of igneous rocks more than 90 years after the publication of Bowen's foundational text. Synchrotron-based measurements, including X-ray and infrared spectroscopies, diffraction, deformation techniques, XRF analysis, computed tomography and other imaging modalities, create pathways for probing the structural, chemical, and physical properties of igneous materials that are unavailable in conventional laboratory settings. Microanalytical techniques such as LA-ICP-MS, SIMS and EPMA have also seen remarkable technical advances and improvements in spatial resolution and detection limits. These techniques provide unique information for tracing the evolution of igneous systems. This session welcomes contributions highlighting innovative experimental, computational, and analytical techniques that address a wide range of physical and chemical properties of igneous materials, and enhance our understanding of the formation, structure, dynamics, and evolution of the interiors of the Earth and other planetary bodies. https://agu.confex.com/agu/fm22/prelim.cgi/Session/158896 Invited speakers: Ayla Pamukcu (Stanford University) and Maryjo Brounce (University of California Riverside) We look forward to seeing you in Chicago this December!
