Comment: Seems cool, I'll have to check it out.Reports that briefly mention GEOROC don't provide significant coverage because they are passing mentions. We need at least one lengthy paragraph.It seems AI-generated, you are not allowed to use artificial intelligence to generate article content. 🌀Hurricane Wind and Fire, why'd you decline my draft?

GEOROC (Geochemistry of Rocks of the Oceans and Continents) is an online database of published chemical and isotopic analyses of igneous and metamorphic rocks. Its records cover whole-rock samples, volcanic glass, minerals and inclusions, and connect analytical values with information about sample locations, rock types, analytical methods and the original publications.[1] The database was established at the Max Planck Institute for Chemistry and is now maintained at the University of Göttingen.[2]
History
[edit]Construction of GEOROC began in 1998 under Bärbel Sarbas at the Max Planck Institute for Chemistry in Mainz, Germany, and the database became available online in 1999. Its initial subject was ocean island basalt, but the scope was extended to volcanic and plutonic rocks from other tectonic settings and to mantle xenoliths.[2]
GEOROC and the Petrological Database of the Ocean Floor (PetDB) were developed at about the same time using a shared relational design. The structure, published in 2000, separates samples, analyses, methods and references into linked tables rather than treating each publication as an isolated spreadsheet.[1] In 2021, responsibility for GEOROC was transferred to the University of Göttingen. The Digital Geochemistry Infrastructure project began redeveloping it as GEOROC 2.0, with changes intended to support dataset deposits, persistent identifiers and exchange with other geochemical data systems.[3]
Contents and access
[edit]The database contains major- and trace-element concentrations, radiogenic and non-radiogenic isotope ratios and analytical ages. These measurements are associated with metadata including geographic position, sample material, petrographic description, geological age and tectonic setting. Method records can include the instrument, laboratory, uncertainty and reference-material measurements reported by the source publication.[1]
Users can search the database by geography, rock or mineral name, tectonic setting, chemical constituent and bibliographic reference. In addition to query results, GEOROC provides precompiled files organized by rock type, mineral, tectonic setting or geographic region.[2] The underlying values are transcribed from the published literature, and results retain citations to those original sources.
Research use and limitations
[edit]GEOROC is used to assemble regional and global geochemical datasets. Zhang and colleagues used its records with geographic information system methods to examine the distribution of alkaline rocks through geological time.[4] Other studies have drawn on it to compare lithium in volcanic-arc magmas[5] and to investigate geochemical variation among volcanic systems.[6]
Literature-derived databases reflect where samples have been collected, which rocks have been studied and which results authors have published. Consequently, apparent geographic or temporal patterns can include sampling and publication biases. Studies using GEOROC commonly filter duplicate, altered or incomplete records and return to the cited papers to evaluate analytical context.[6] Reviews of geochemical data infrastructure have also identified differences in metadata standards and vocabularies as obstacles to combining GEOROC with other databases.[3]
