*Apologize for multiple postings* Hello everyone, Here is a short announcement of a 4-days Workshop entitled: "Recent Developments and Applications in earth sciences of electron probe micro-analysis" that will be offered VIRTUALLY in the period 27-30 March 2023. The workshop is on the use of the electron probe microanalyzer (EPMA) with particular emphasis on modern developments and geological applications. Within the next weeks, will present you (SHORTLY) our speakers (given in alphabetical order of the last name). Therefore, it is not on purpose, however, will start from myself! *Ioannis Baziotis **is assistant professor in mineralogy and petrology at the Agricultural University of Athens. He studies igneous and metamorphic rocks, along with meteorites (chondrites, and achondrites). He focuses on high pressure phases by applying instrumental techniques, and thermodynamic relations. He is author and co-author of more than 50 peer-reviewed scientific papers in highly ranked International Journals. * *The rest of our Speakers to be presented are: *James Day (University of San Diego, SCRIPPS), John Donovan (University of Oregon), Stamatios Flemetakis (University of Muenster), Ariadni Georgatou (GNS Science), Anette von der Handt (University of British Columbia), Ery Hughes (Te Pū Ao | GNS Science), Rosie Jones (WDS Product Manager at Oxford Instruments NanoAnalysis), Pierre Lanari (University of Bern), Stuart Kearns (University of Bristol), and Lee M. Saper (University of Edinburgh). 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 basic theory of electron probe microanalysis, the statistics behind microanalysis, but also more advanced theory on k-ratios and standards. Also, will taught about X-ray maps and their usage in metamorphics, trace element analysis for investigating various processes (e.g., mantle processes and sulfide crystallization). Furthermore, the usage of WDS analysis using SEM instrument. Finally, two LIVE demonstrations using JEOL and CAMECA instruments of how someone is measuring on EPMA will be given as well. ALL the previous will be given for a nominal fee of *30 euros *that will cover the basic expenses for the hosting platform etc. All the participants will have access on the recorded material up to 2 weeks after the end of the workshop.
