Dear Colleagues, We are writing to announce the second Gordon Research Conference (GRC) on Geochronology (https://www.grc.org/geochronology-conference/2023/<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.grc.org%2Fgeochronology-conference%2F2023%2F&data=05%7C01%7Cbschoene%40princeton.edu%7C5d68a20e6a214bedc00608dad480ff12%7C2ff601167431425db5af077d7791bda4%7C0%7C0%7C638055947737930674%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=WT8c0%2Bc3JretmkZ%2FXTqokUDiZnvZpcSVqjkUDEjWI0I%3D&reserved=0>). This GRC conference will be held August 13-18, 2023 at Mount Snow, Vermont. The theme of the 2023 GRC is the "Timing, Tempo and Drivers of Lithospheric Evolution.” We have a lineup of confirmed discussion leaders and speakers, which is provided below. These include geochronologists as well as scientists whose work is heavily influenced by geochronology. The GRC provides an immersive experience for five days with colleagues in a collegial environment. We hope you will join us next August. There is a limit of 200 participants, so apply to be a poster presenter soon at the website listed above. The 2023 GRC will be preceded by a Gordon Research Seminar (GRS) (https://www.grc.org/geochronology-grs-conference/2023/<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.grc.org%2Fgeochronology-grs-conference%2F2023%2F&data=05%7C01%7Cbschoene%40princeton.edu%7C5d68a20e6a214bedc00608dad480ff12%7C2ff601167431425db5af077d7791bda4%7C0%7C0%7C638055947737930674%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=X4nYQMoiKS0a5pFipZr41TTi%2FYHYE5IkV9b9NdxrxW4%3D&reserved=0>) planned by and for students and early career researchers. The inaugural Geochronology GRS will run August 12-13 at Mount Snow, and will include a mentoring session highlighting different career paths and how to overcome common challenges faced by early-career researchers. We hope that group leaders will encourage and support your research groups to attend both the GRS and GRC. There will be an application process, to be announced later, for funding to support attendance from students and postdocs. GRC has limited grants available to help subsidize participation for individuals from underrepresented groups.
