Mission Statement

EarthChem enables innovation and advances in the Earth, Ocean, and Environmental Sciences through our data services.

We promote community-driven discovery, accessibility, interoperability, and reusability of geochemical, petrological, and related data.

Data Services

Data Mining and Analysis

PetDB is a searchable database of geochemical data from igneous and metamorphic rocks. Data are compiled primarily from the published literature.

EarthChem Portal is the one-stop-shop for geochemical data that gives users the ability to search federated databases including PetDB, SedDB, NAVDAT, MetPetDB, the USGS National Geochemical Database, GEOROC, and GANSEKI simultaneously.

Data Publication and Preservation

EarthChem Library is an open-access repository for geochemical datasets. The ECL offers a complete suite of services for data preservation and access, including long-term archiving and registration of data with Digital Object Identifiers (DOIs).

Earthchem is part of an ecosystem of related projects governed by IEDA2
