Colleagues – A reminder that the Abstract deadline of Friday April 11, 2025 (11:59 pm CT, USA) has arrived for the 5th biennial North American Workshop on Laser Ablation (NAWLA) (https://www.nawlaworkshop.com/), which will be held at The University of Tennessee in Knoxville TN (USA) from Tuesday June 3rd to Thursday June 5th, 2025. Abstracts must be submitted from the NAWLA website (https://www.nawlaworkshop.com/abstract-and-poster-submission). Contributed abstracts for oral and poster presentations are welcome on topics related to Geo- & Bio-Analysis including Geo- & Bio-imaging, Advances in Geochronology and Isotope Geochemistry, Calibration Strategies and Reference Materials, New Instruments/Methods, and Applications of LA Methods to Geology, Biology, Environmental Science, Archeology, Anthropology, Forensics, Material Science Keynote Speakers are: Dr. Kharmen Billimoria, National Measurement Laboratory at LGC, UK, ‘Quantitative approaches for bioimaging’ Dr. Birk Haertel, University of Calgary, Canada, ‘Method development and first results from zircon U/Pb-(U-Th)/He-Raman triple-dating’ Prof. Matthieu Baudelet, University of Central Florida, USA, ‘From crush to real thing: the love story of matrix-matched standards for hard biomaterials’ Dr. Benjamin Farcy, NASA Goddard Space Flight Center, USA, ‘PLASMA: A miniature LA-MIP-MS for geochemical analysis of planetary surfaces’ Pre- and post-workshop activities will be held in conjunction with NAWLA: Oak Ridge National Laboratory, located nearby, will hold a separate ORNL facilities tour and workshop (https://www.nawlaworkshop.com/) on Monday, June 2nd. On Friday June 6th, a separate workshop on Reference Material Development for Common-Pb-Mineral U-Th-Pb Geochronology (https://www.nawlaworkshop.com/geochron-friday) will be held at The University of Tennessee. It is sponsored by an award from the AGeS3-TRaCE program supported by the National Science Foundation. Confirmed Speakers are: Paul Sylvester (Texas Tech Univ) – “Overview of the status and needs for development of reference materials for common Pb-rich mineral U-Th-Pb geochronology” Kate Souders (USGS/Denver) – “Time-resolved laser-induced U-Th-Pb fractionation patterns of common Pb-rich minerals and their bearing on reference material development” Jay Thompson (USGS/Denver) – “Data reporting for U-Th-Pb geochronology of common Pb-rich minerals determined by LA-ICP-MS” Mark Schmitz (Boise State University Isotope Geology Laboratory) - "Tandem in situ and isotope dilution U-Pb geochronology applied to apatite and garnet: harnessing 3D ’Total Pb/U isochrons’ and petrochronology to build a better library of reference materials" Contributed oral and poster presentations documenting promising reference materials are encouraged. The convenors will contact potential presenters to discuss follow-up details to build the workshop program beginning April 21st. On behalf of the convenors, we hope to see you in Knoxville!
