*Apologize for multiple postings and the long email* *May the New Year bring you an abundance of health and happiness, filling each day with a lot of energy, harmony and joy.* Hello everyone, "*Recent Developments and Applications in earth sciences and archaeology of electron probe micro-analysis*". A virtual workshop that will be offered in the period 24-27 March 2025. The workshop is on the use of the electron probe microanalyzer (EPMA) with particular emphasis on modern developments and geological applications. *New for this year*: *Geo-archaeology* presentations featuring case studies from *Pompeii*, and the use of *meteorite iron during the Ancient Egypt era* . Meet our lecturers (vol.1): *John Donovan* is the former director of the CAMCOR MicroAnalytical Facility at the University of Oregon. Since 2021 he holds a courtesy appointment in the Department of Geological Sciences at the University of Oregon. John is also president of Probe Software, Inc. a company that distributes software for Electron Micro Probe Analyzer (EPMA) acquisition, automation and analysis. John was awarded the MAS Macres Award in 1990 and the Presidential Science Award in 2010 for his software development efforts. He is actively engaged in raising public awareness regarding scientific issues and lectures on such topics to general audiences. He continues to develop EPMA acquisition, automation and analysis software. His most recent efforts involve efforts to identify and procure high purity synthetic mineral standards for global distribution, new developments in characterizing and correcting for dead time effects in WDS detectors, and investigations into modeling backscatter and continuum productions in compounds. *Ariadni Georgatou* is a post-doc petrologist at the University of Athens, in the field of economic geology, investigating specific magmatic processes that contribute to ore formation. She completed both her Msc and PhD at the University of Geneva in Switzerland, where she specialised in the topic of sulfide saturation in volcanic rocks and its role to porphyry and epithermal deposit formation. Ariadni then proceeded with post-doc studies as a SNSF mobility fellow to conduct research at GNS Science in New Zealand and study the behavior of metals and volatiles in Brothers submarine volcano associated with sea floor massive sulfide deposit. Her research made use of several micro-analytical techniques including SEM, EPMA, LA-ICP-MS and QEMSCAN. *Celestino Grifa* is Associate Professor at the Department of Science and Technology (DST) at University degli Studi Del Sannio. His is Member of the Scientific Council of the Interuniversity Research Center CRACS (Center for Research in Archaeometry and Conservation Science) between the University of Sannio and the University Federico II of Naples; member of the Board of Directors of the University of Sannio; member of the Board of Directors of Italian Association of Archaeometry; member of the Board of Teachers of the Doctoral Program in Science and Technology for the Environment and Health (STAS) and the National Doctoral Program "Heritage Science" with administrative headquarters the University La sapienza of Rome, and responsible for the Laboratory of Optical and Electronic Microscopy of the DST. His scientific activity, evidenced by more than 100 scientific publications, is focused on the study and characterization of materials of the historical built (stones, mortars, plasters) and archaeological finds (ceramics, metals, pigments), boasts collaborations with research institutions at national and international level. He also conducts research on alkaline volcanic rocks of the Plio-Quaternary Campanian Volcanic Province (Ischia, Campi Flegrei and Somma-Vesuvius), Cretaceous magmatism of the Italian peninsula and Cenozoic igneous rocks of Madagascar. *Chris Hayward* is a geologist and EPMA specialist at University of Edinburgh, Scotland. He has run EPMA labs at Cambridge (2002-2007) and Edinburgh (2007-present). These labs have had diverse ranges of clients and samples including most types of minerals in terrestrial and extra-terrestrial samples, tephras, archaeomaterials, ores, and experimental alloys for aerospace applications. Published research interests have included the formation of the Witwatersrand gold deposits of South Africa, developments of new analytical protocols for EPMA of crypto-tephras and Ni-base superalloys, tephrochronology, Icelandic volcanism, and geoarchaeology - especially quarrying and stone-working in ancient Greece, field survey, and palaeo-topographic reconstruction of archaeological sites. *Anette von der Handt* is currently a Research Associate in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia, Vancouver. She has close to two decades of electron microprobe experience under her belt and worked with a wide range of makes and models through the years. She received her M.Sc. in Geology from the University of Bonn and a Ph.D. in Geochemistry from the Max-Planck Institute for Chemistry, Germany. Her current research interests include developing microanalytical methods with a special focus on trace elements, ultra-light element (B, C, N, O) analysis, and low kV applications using soft X-ray emission spectroscopy. Based on our experience, we are pretty sure that this workshop will provide VALUABLE new knowledge for the undergraduate students, postgraduates, PhD, postdocs, senior scientists, and lab managers. Every participant will have the chance to learn the basics and more advanced aspects of electron probe microanalysis. The early registration fee is 40 euros and includes the attendance at the workshop, and FULL access to online material (recordings, presentations, transcripts). Late Registration (after 28th February 2025) is possible, however, the registration fee is increased by 30% at 52 Euros. Therefore, book your virtual seat as soon as possible.
