The service provides a platform for data sharing and queries serving researchers in geology and related sciences. It focuses especially on data related to chemistry, chronology, and petroleum exploration and production. The portal originated with support of the U.S. National Science Foundation to give federated access to major geochemical databases from the U.S. Geological Service and other international providers.
API methods support search for datasets from published research by author name, article title, journal name, year of publication, or keyword character string. Results can be filtered by date range, either for publication or data collection, and location specified as a mapping polygon or with less specific identifiers. Results may also be limited to specific characteristics of data samples such as materials or chemical compounds and chonological age of the minerals sampled.
