Non-traditional stable isotopes, including Fe, Mg, Ca, Ti, and others, emerged around 2000 with the development of MC-ICPMS technology. The measurement of non-traditional stable isotopes has opened new avenues of research in earth science, biomedical science, environmental science, and cosmochemistry. In recent years, the volume of data within this field has grown exponentially. Our team is committed to establishing a comprehensive and user-friendly non-traditional stable isotope database, which will serve as an essential resource for researchers and students. Our goal is to promote the development and application of non-traditional stable isotopes and to support cutting-edge research in isotope geochemistry.
