Home: Earth Sciences: Geochemistry: Databases: Geochemical Analyses
    Multiple on-line chemical databases, including summary data on the geochemistry of all reservoirs in the Earth, partition coefficient data for all types of rocks and minerals and for every element, and a petrologic and chemical database of seafloor samples from a variety of tectonic environments. Also includes on-line modeling software, and a schedule of presentations and workshops by organization staff.

  • PETROS Igneous Petrology Databank
    A worldwide data bank of major element chemical analyses of igneous rocks. Includes 37,300 major element chemical analyses divided into 307 major groups representing geographic areas or petrologic provinces. Also includes 468 average igneous rock compositions, a bibliography of information sources, and complete format/operating instructions for PETROS.

  • Emission Database for Global Atmospheric Research
    Global inventories of direct and indirect greenhouse gas emissions, including halocarbons. Data are available in tables and map summaries. Compiled compounds include carbon dioxide, methane, nitrous oxide, nitrogen oxide, sulfur dioxide, carbon monoxide, non-methane volatile organic compounds, and chlorofluorocarbons. Registration is requested prior to accessing data.

  • The Index to Marine Geological Seafloor Samples
    Also known as the Curators' Database, this is a cooperative effort among nineteen oceanographic institutions and governmental agencies to provide information on the contents of their collections of seafloor samples to researchers. More than 100,000 samples can be searched on-line by specifying any combination of institution, cruise, ship, collection date, water depth, sampling technique, or geographic location.

  • GEOROC Geochemical Database
    GEOROC (GEOchemistry of Rocks of the Oceans and Continents) is a searchable collection of more than 50,000 analyses from different tectonic settings. Queries can be made based on bibliography, tectonic setting, geography, chemistry, and petrography.
