Dear Colleagues, I’m very pleased to announce the launch of Advances in Geochemistry and Cosmochemistry (AGC -http://www.agcj.org<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.agcj.org%2F&data=05%7C02%7CcooperG3%40cardiff.ac.uk%7C4e069ea7aa7b4cb4c57a08dd0f9e327a%7Cbdb74b3095684856bdbf06759778fcbc%7C1%7C0%7C638683894341980639%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=mhqcporTikCZzMtj7pit2aRa8JZEQL25xQqvoSCDSq0%3D&reserved=0>), a new, community-run, and Diamond Open Access journal, which I’m sure will be of great interest to many in our community. We intend to open for submissions from January 20, 2025. AGC offers a unique opportunity to publish in a journal that is entirely managed by scientists, free from the constraints of large-scale publishers. It is part of the Guild of Diamonds, joining a wider collective of established Diamond Open Access journals in Earth Sciences, including Seismica, Volcanica, and Tektonika. The journal will focus on long-format submissions from the broad fields of geochemistry and cosmochemistry, comparable in scope to those found in GCA or Chemical Geology. A highly capable and diverse team of editors has been assembled to handle submissions and can be browsed here https://journals.uu.se/AGC/handlingeditors<https://eur03.safelinks.prote…amp;reserved=0>. We are very keen to encourage submissions from across our field and to ensure the journal is well-prepared for its launch, we’re asking people to register their interest in submitting to AGC via this form:https://forms.gle/GHHmHioBdRSijPas7<https://eur03.safelinks.protect…amp;reserved=0>. This will help us gauge the volume of anticipated submissions and plan accordingly to manage the workloads of our team. If you are planning a submission, please make sure to follow the instructions and author guidelines here https://journals.uu.se/AGC/about/submissions<https://eur03.safelinks.pro…amp;reserved=0>. For more information about the journal and the team behind it, please visit our website:https://journals.uu.se/AGC/about/editorialTeam<https://eur03.saf…amp;reserved=0>. Thank you for supporting this initiative. We’re really looking forward to your contributions and feedback as we build this journal together. All the best, Elliot Carter (on behalf of the AGC Editorial Team) Dr Elliot Carter (he/him) Lecturer in Geology School of Geography, Geology and the Environment Keele University
