MAPT session information: "The role of microanalysis and microtextures in understanding magmatic processes" Keynote: Adam Kent (Oregon State) The study of petrographic textures has always been a key part of igneous petrology, and the microscope remains a fundamental tool in understanding magmatic systems. In recent years, though, a range of technological and analytical advances has opened up new frontiers in petrographic research. We can now investigate microscopic textures at ever-smaller scales, and even in 3-D. Furthermore, we can integrate in situ geochemical analyses of elements and their isotopes to trace petrogenetic timescales and processes. These opportunities have led to significant advances in our understanding of magmatic processes. This session will welcome contributions on the application of microanalysis and microtextural studies to igneous rocks. Examples may include microgeochemical analysis; in situ dating; micro-scale analysis of textures and structures in magmatic rocks; and the use of microscopic features in understanding rates and timescales of magmatic processes. MAPT conference information: The 2009 Annual Meeting of the Mineralogical Society of Great Britain and Ireland has the title 'Micro-Analysis, Processes, Time (MAPT)'. The conference will be held in Edinburgh from 31st August to the 2nd September, with workshops and field trips immediately before and after these dates. The meeting is being organised in conjunction with: the Deutsche Mineralogishe Gesellschaft, the Société Francaise de Mineralogie et de Cristallographie, and the International Association of Geoanalysts. The lead convenor is Professor Simon Harley of Edinburgh University and chair of the Metamorphic Studies Group of the Mineralogical and Geological Societies. Micro-analytical and micro-textural information is now central to many new observations in the Earth sciences, and it is critical to the testing and development of hypotheses related to Earth processes and behaviour on all time and length scales. MAPT will provide a forum for the presentation and discussion of the many recent advances in Micro-Analytical techniques (including both chemical and textural analysis). MAPT will focus also on how these advances impact on our understanding of mineralogical-geochemical Processes, their timescales of development, and the consequences for the measurement of Time in the Earth Sciences. In the last ten years new developments in instrumentation have led to considerable improvement in very high spatial resolution chemical analysis and textural mapping in the mineralogical-geological sciences. These developments include: determination of stable and radiogenic isotopes by ion microprobe (SIMS) and LA ICP-MS; use of electron backscatter diffraction (EBSD) by SEM; controlled ion thinning techniques with TEM; synchrotron x-ray techniques and widespread application of Raman Spectroscopy. The new methods, in concert with longer-established techniques (e.g. electron microprobe analysis, petrographic analysis using optical microscopy, cathodoluminescence imaging and back-scattered imaging) enable more detailed and higher resolution chemical, textural and crystal structure observations to be made in-situ. These in turn provide more powerful and stringent tests of models of Earth behaviour. Thus the understanding of large scale processes (for example: the evolution of the Archaean crust, or the mineralogy of the deep mantle, or climate change records) are often underpinned by a wide variety of microscopic investigations of minerals, rocks and fossils. MAPT will address both the actual development of new micro-analytical instrumentation and techniques, and the new information and ideas that are arising from application of these techniques and older techniques of microscopic observation and analysis. A list of suggested sessions is given on the following page. Proposals for other sessions are welcome. Presentations will be given both orally and by poster. ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
