Our Mission


The mission of the division is to bring together scientists interested in geochronology, to provide a suitable forum for presentation and discussion of problems and opportunities in geochronology, to stimulate research and teaching in geochronology, and to act as an organized group in promoting these objectives within the framework of the Geological Society of America.

Welcome to the Geochronology Division!


Our community spans a wide range of geoscientists with interests and expertise in the measurement of geologic time, laboratory method development, and diverse applications to understanding Earth Processes.

Upcoming Events in Geochronology


  • Geochronology Gordon Research Seminar for students and early career scientists

    Saturday, August 16 - Sunday, August 17, 2025
    The Geochronology GRS provides a unique forum for young doctoral and post-doctoral researchers to present their work, discuss new methods, cutting edge ideas, and pre-published data, as well as to build collaborative relationships with their peers. Experienced mentors and trainee moderators will facilitate active participation in scientific discussion to allow all attendees to be engaged participants rather than spectators.

  • Geochronology Gordon Research Conference

    Sunday, August 17 - Friday, August 22, 2025
    The Geochronology GRC is a premier, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages. The conference program includes a diverse range of speakers and discussion leaders from institutions and organizations worldwide, concentrating on the latest developments in the field. The conference is five days long and held in a remote location to increase the sense of camaraderie and create scientific communities, with lasting collaborations and friendships. In addition to premier talks, the conference has designated time for poster sessions from individuals of all career stages, and afternoon free time and communal meals allow for informal networking opportunities with leaders in the field. Geochronology quantifies geological time as a means for integrating diverse geological records, establishing cause and effect, constraining the rates and durations of fundamental geological processes and phenomena, and testing time-dependent models for system evolution. The sessions explore the timing, tempo, and drivers of Earth’s climate at the interface of Earth system topics, over a range of geological timescales and throughout Earth history. The aim of the conference is to foster interactions among scientists and formulate strategies for synergistically exploiting opportunities and reducing limitations of current technology, infrastructure and scientific culture. We invite contributions that exploit and apply geochronology to a wide range of topics in Earth’s climate, describe novel approaches, highlight geochronologic needs, and foreshadow future developments.

Announcements

  • Urgent Call for Nominations: Research Grants Committee Member-at-Large

    At the close of Committee Nominations on 15 June, we did not receive any nominations for the Geochronology Member-at-Large position on the GSA Research Grants Committee. Each year, graduate research grant proposals are submitted in geochronology and related fields, and GSA needs qualified reviewers to ensure these proposals receive the attention and expertise they deserve.

    We’re asking members of the Geochronology Division to consider stepping up and nominating themselves for this important volunteer role.

    🔹 Position: Member-at-Large, Geochronology – Research Grants Committee
    🔹 Term: 1 December 2025 – 30 June 2028 (3 years)
    🔹 Time Commitment: Proposal review season runs March–May; committee is inactive the rest of the year.

    The Nominations Portal has been reopened through Wednesday, 18 June. To access it, please contact Macie Schiller (mschiller@geosociety.org) for the temporary password and with any questions.

    This is a vital opportunity to support graduate students and contribute your expertise to the future of geochronology. Please consider nominating yourself today!
