The Significance of Geochemical Data Bases and the Impact of GEOROC and PetDB
No full textThe GEOROC and PetDB databases have compiled peer-reviewed literature data on geochemical compositions of igneous rocks and minerals for >25 years (https://georoc.eu/; https://search.earthchem.org/). While initially the focus lay on ocean island and mid-oceanic ridge basalts, respectively, both databases have widened their scope and now include the complete compositional range of igneous rock types as well as mantle xenoliths and minerals, comprising: 22 geological settings; 351 lithologies; 533 mineral species; and all common major, trace and rare earth elements, isotopic ratios as well as analytical ages. Today, the two databases contain >47 million single data values from ~27,000 publications, with 28,942,143 in situ and 18,330,454 bulk data points. Continued data curation of PetDB and GEOROC ensures that the databases continue to grow. The EarthChem Portal enables harmonized access, filtering and download from the combined databases (http://portal.earthchem.org/).
The comprehensive data collections offered by PetDB and GEOROC present a unique opportunity to the research community to undertake advanced analysis of large-scale regional and global datasets. New research questions have been tackled, making PetDB and GEOROC an essential tool for digital geochemistry. Both databases have accumulated more than 4000 citations ranging from highly detailed, regional comparative research to machine learning studies using thousands of data points. We present a detailed analysis of the usage of GEOROC and PetDB data products to highlight the wide range of research topics that GEOROC and PetDB have supported, and the impact of global geochemical data compilations on past, present, and future trends in the Earth System Sciences
Unlocking the Power of Mineral Data in Global Geochemical Databases
No full textNovel methods of data analysis have led to numerous innovations in mineralogical research in recent years, requiring increasingly larger precompiled datasets. Whilst dedicated, high-quality expert compilations are invaluable for addressing specific research questions, comprehensive and curated global databases, such as GEOROC and PetDB, are essential for realising the full scientific potential of mineralogical data.
Since the late 90s, the GEOROC and PetDB databases have collated, archived and curated over a century’s worth of geochemical analyses of natural minerals. The databases currently contain 17,531,666 and 2,664,189 individual mineral data values, respectively, which makes up over half of their total data holdings. These data are compiled together with carefully selected metadata that capture the diversity of mineral geochemical data, while also enabling targeted data quality assessment.
To continue to obtain new insights from the accumulated data collected by mineralogists worldwide, our community needs to come together to ensure the continued improvement and sustainability of such curated databases

Synchronizing GEOROC and EarthChem towards Global Geochemical Data Exchange
No full textGEOROC and EarthChem provide services for open data publication, archiving, and interactive access of geochemical and isotopic data of igneous and metamorphic rocks, minerals and inclusions. The two data providers have collaborated since the early 2000s to deliver consistent and complementary data to the geochemistry community. Curation work for PetDB and GEOROC relies on a strong foundation of consultation with the broader geochemical community, to establish which dataset quality related metadata needs to be included to provide end-users with truly reusable datasets. Data exchange is currently implemented through the EarthChem Portal (ECP). The ECP was developed as a global open data service to the geochemical, petrological, mineralogical, and related communities. It provides a single point of access to >45 million analytical values for >1 million samples, aggregated from independently operated databases (PetDB, NAVDAT, GEOROC, USGS, MetPetDB, DARWIN).
In an effort to improve the FAIRness of their data services and the interoperability of their data systems, a new suite of API-driven architecture is being developed by both systems. EarthChem and DIGIS (Digital Geochemical Data Infrastructure initiative for GEOROC 2.0) have committed to cooperation on system architecture design, data models, data curation, methodologies, best practices and standards for their geochemical data infrastructures. This effort will include working towards harmonized vocabularies for the core database concepts as well as dataset quality information.
These common vocabularies are being developed as part of the Observations Data Model 2 (ODM2) ecosystem. Versioning of the vocabularies will ensure dynamic response to evolving community requirements. This will allow for versatility for expansions to other data types, after more rounds of community consultations to determine best practices. The vocabularies further build on established concepts from other communities, such as mineralogy and chemistry.
These common vocabularies developed between EarthChem and DIGIS will be the foundation of future seamless API-driven data exchange that can act as a prototype for the distributed data framework envisioned by OneGeochemistry
