The Geoscientific Data & Discovery Publishing System (GDD) is a data publishing repository for geological scientific data mainly from solid and surface Earth sciences, which involves a wide range of disciplines, including data of geology, geophysics, geochemistry, mineral deposits, hydrogeology, engineering geology, environmental geology. It is affiliated to the National Geological Archives of China (NGAC), which is an affiliated institution of the Ministry of Natural Resources and China Geological Survey, and holds the largest collections of geological data in China. The data published and preserved in GDD are from not only geoscientific data in China but also those in other countries worldwide. All the datasets and data papers are under peer-review and published with Digital Object Identifiers (DOIs). All datasets are fully open accessible through the GDD websites. The data papers in GDD are periodically published since 2017. From 2022, all the data papers of GDD will be published in the peer reviewed journal Acta of Geoscientific Data & Discovery. In using and implementing the WDS data sharing principles, as well as the FAIR principles, The Acta of Geoscientific Data & Discovery will update its data publishing and sharing guidelines, including procedures, network with journals and citation data bases, etc.
