Workshop Description


Matthew Fantle (, Juraj Farkaš (, Elizabeth Griffith (, Stein Jacobsen, and Théo Tacail (


The aim of this one-day workshop is to bring together people interested in the application of calcium (Ca) isotopes to questions/topics relevant within the earth, planetary and environmental sciences, as well as the frontier fields of biomedicine and archeology. We recognize that a cohesive, well-connected research community is best able to solve a range of problems, promote the use of Ca isotopes, and push proxy development forward. The workshop will be active in its nature, promoting discussion focused on the themes listed below. The workshop will also offer a unique opportunity for the demonstration of new technology relevant to Ca isotope analysis, specifically a next generation collision-cell MC-ICP-MS (Sapphire from Nu Instruments) housed at Harvard University (

Themes for the workshop include, but are not necessarily limited to:  

  1. (1)New Developments and Old Issues in Ca Isotope Analysis

  2. (2)Elucidating Geochemical Cycles at Local, Regional and Global Scales using Ca Isotopes

  3. (3)Ca Isotopes in Deep Time: Potential and Limitations

  4. (4)Numerical Modeling of Ca Isotopes in Terrestrial and Marine Settings

  5. (5)New Frontiers in Ca Isotope Geochemistry

We ask that each participant prepare, in advance, a 2-minute /1-slide presentation that fits within one of the themes. The brief talk should highlight a particular question, topic, or problem that the researcher is interested in, and that can be used to stimulate discussion in breakout groups following the prepared mini-presentations. It is our hope that the workshop will serve as platform for the development of a Ca isotope community. This includes the improvement of interpersonal relationships in an informal setting, the formation of new research collaborations, the community-wide adoption of solutions to common problems, and the enunciation of key future research directions.
