EarthChem is a Geochemistry Information Network; Portal to Distributed Geochemical Databases

EarthChem is a community-driven effort to facilitate the preservation, discovery, access and visualization of the widest and richest geochemical datasets. 

Search seamlessly across multiple databases
The EarthChem Portal offers a "one-stop-shop" for geochemistry data of the solid earth with access to complete data from multiple data systems. The portal features mapping and visualization tools.

Access igneous geochemistry and topical data collections
Earthchem builds and maintains topical data collections and provides access to topical datasets developed and maintained by partner projects.  For example, the EarthChem Deep Lithosphere Dataset contains geochemical and petrological data from lower crust and upper mantle xenoliths.

Search, download or contribute data compilations and tools
The EarthChem Geochemical Resource library (GRL) is a collection of datasets, tools, and resources relevant to the field of geochemistry contributed by the geochemistry community.
