  • Geochron 1.0 Release

    June 2011: EarthChem is pleased to announce the release of Geochron, an application that helps with the onerous task of data management for geochronological and thermochronological studies. Geochron was developed in collaboration with the EARTHTIME effort and worked with expert groups from the Ar-Ar, U-Pb, (U-Th)/He, and CRN communities to establish reporting requirements and XML schemas to be used for transferring data from reduction programs to database. Access to these programs is available at the Geochron website.


    Users can now upload data and metadata to the Geochron system, or search data in Geochron by age, method, mineral, or location parameters. Enhancements to the search interface will be made in the near future. Geochron works with the System for Earth Sample Registration (SESAR) to use the IGSN Unique Identifiers for samples. EarthChem, Geochron, and SESAR are all part of the IEDA community-based data facility funded by the National Science Foundation.

  • EarthChem KML for Google Earth

    June 2011: The EarthChem Google Earth KML file provides end-users with an intuitive interface to all EarthChem samples (including NAVDAT, PetDB, GEOROC, USGS, GANSEKI, SedDB, and MetPetDB). To view EarthChem samples in Google Earth, simply load the EarthChem.kml file and zoom to your desired location. There is currently a limit of 1000 samples per page view, but zooming in to a location will provide all samples. To view sample details, click on the individual sample icons.
