  • New Data Submission Templates

    May 2011: Data Submission Templates [link] have been posted to help authors submit their data to the GfG systems. These templates are customized for different analytical techniques (electron microprobe, mass spec) and materials (bulk sample, mineral, melt inclusion, vent fluid) and help authors to document their data according to the recommendations of the Editors' Roundtable. Authors can also add their own fields to the templates. Instructions and suggested vocabularies are included in these .xls workbook templates.


    The templates provide a standardized way to submit data to GfG, including our Geochemical Resource Library (GRL) and the GfG databases PetDBSedDB, and VentDB.


    The full list of templates is posted at the EarthChem website:
