New major and trace element data on samples collected during the IODP (International Ocean Discovery Program) Expedition 396, ODP (Ocean Drilling Program) Leg 104, and DSDP (Deep Sea Drilling Project) Leg 38 on the Vøring margin, including 209 whole rocks analyses on hard rock samples (basalt, granite, andesite, dacite and rhyolite), 13 whole rock data on ash layers, and 381 in situ pXRF analyses on basaltic rocks. The DIGIS geochemical data repository is a research data repository in the Earth Sciences domain with a specific focus on geochemical data. The repository archives, publishes and makes accessible user-contributed, peer-reviewed research data in standardised form (EarthChem Team, 2022, https://doi.org/10.26022/IEDA/112263) that fall within the scope of the GEOROC database (https://georoc.eu). All submissions of new data will be considered for inclusion in the GEOROC database. It is hosted at GFZ Data Services through a collaboration between the Digital Geochemical Data Infrastructure (DIGIS) for GEOROC 2.0 (https://digis.geo.uni-goettingen.de) and the GFZ Helmholtz Centre for Geosciences. 

The mid-Norwegian margin is one of the best studied volcanic rifted margin on Earth. Geophysical investigations have demonstrated the presence of well-developed seaward-dipping reflectors, landward-dipping reflectors, marginal highs, ash layers and sill complexes. These features have been proven to consist of magmatic rocks through the international Deep Sea Drilling Program (DSDP expedition 38, 1974), Ocean Drilling Program (ODP expedition 104, 1985), International Discovery Program (IODP expedition 396, 2021), and commercial drilling. A total of fifteen drill cores penetrated magmatic rocks that formed between 57 and 50 million-years ago. Here we provide a compilation of all new and published data for magmatic rocks in the fifteen drill cores (n= 563). This dataset represent a resource for examining the origin of magmatism associated with continental breakup and rifted margin formation, particularly the formation of excess magmatism compared to normal mid-oceanic spreading ridges, mantle-crust interaction, and the linkage of magmatism to global hyperthermal events on Earth’s surface.

Compilations of previously published data are also made available on the GEOROC website (https://georoc.eu) as Expert Datasets.
