This newsletter summarizes new features and improvements at EarthChem as well as recent community engagement and featured datasets. To subscribe to future quarterly newsletters please click here.

Recent Improvements

  • EarthChem Library (ECL) version 3.6.4 was released. This new version allows users to select the Creative Commons license that they would like to associate with their dataset. Users can now choose between four different licenses, providing more flexibility for users to allow reuse for commercial purposes or to make the dataset public domain. See more release notes here.
  • The PetDB Search application has been completely redesigned to allow for easier data searching and integration. This new version enhances usability and supports new functionality such as: search by chemical composition; expanded map search, including a southern polar projection; search by age; search by International Geo Sample Number (IGSN); and plotting data as TAS and Harker diagrams. Please write to us at with any feedback or comments.

Featured Datasets

  • Major element data for olivine, orthopyroxene, and spinel within peridotites from the Southwest Indian Ridge. View in the ECL.
  • Characterization of plagioclase hosted melt inclusions in A91-1R (Blanco Transform Fault). View in the ECL.
  • LA-ICP-MS apatite fission track and U-Pb dataset for southern Baffin Island, Nunavut, Canada. View in the ECL.
  • Hadean silicate differentiation preserved by anomalous 142Nd/144Nd ratios in the Reunion hotspot. View in PetDB.
  • Extensive young silicic volcanism produces large deep submarine lava flows in the NE Lau Basin. View in PetDB.
  • Mantle source heterogeneity for South Tyrrhenian magmas revealed by Pb isotopes & halogen contents of olivine-hosted melt inclusions. View in PetDB.

EarthChem Community

The EarthChem Team attended the AGU Fall Meeting held in Washington D.C. See more information below about our presentations at AGU, which included presentations about open and FAIR Data and participation in a Townhall regarding geochemical data standards. If you were not able to catch up with us at AGU, contact us at info@ with questions or comments about our resources.

  • Building a Global Network of Geochemical Data: This Townhall discussed developing geochemical data standards in the Earth Sciences and opportunities for a global geochemical data network. To learn more, please refer to the presentation here.
  • Boosting Data Science in Geochemistry: We Need Global Geochemical Data Standards and Networking!: In this presentation, Dr. Lehnert talked about how can we develop global standards that would allow for connecting and exchanging data among the geochemical data systems. The presentation can be found here.
