EarthChem - Advanced Data Management for Solid Earth Geochemistry

The quantity and detail of geochemical data now available requires the assistance of modern information technology approaches in order to use the data in the most flexible, complete and effective way. This site contains links to three main databases: GEOROC, NAVDAT, and PETDB. GEOROC, NAVDAT and PetDB have produced relational databases that serve geochemical analyses of igneous rocks and minerals together with a wide array of metadata about the samples and the analytical procedure to the broad community of Earth scientists. Collaboration between the three independently developed database efforts has ensured that by sharing the basic data schema employed (Lehnert et al., G3, 2000) the data in the individual databases eventually can be seamlessly integrated through future developments in information management.
