Hein United States Geological Survey (USGS) Pacific Coastal and Marine Science Center, Santa Cruz, 2885 Mission Street, CA 95060, USA Georgy Cherkashov Research Institute of Geology and Mineral Resources of the World Ocean (VNIIO), 1 Angliisky Avenue, 190121 St Petersburg, Russia Abstract This study summarizes a compilation of studies and cartographical work on seabed mineral deposit types in pan-European seas developed under the GeoERA-MINDeSEA project. In total, 692 occurrences and 1194 individual mineral samples of volcanogenic massive sulfides and hydrothermal mineralization, ferromanganese crusts, phosphorites, marine placer deposits, polymetallic nodules, and their associated strategic and critical raw material (CRM) elements have been characterized. The GeoERA-MINDeSEA project has been built based on extensive studies carried out previously, which include geophysical surveys, sampling stations, underwater photography and remotely operated vehicle (ROV) surveys, and mineralogical, geochemical and isotopic studies. This study develops pan-European and national databases, and expands strategic and CRM knowledge through a compilation of mineral potential and metallogenic studies of CRM resources in European seas. For the first time, the GeoERA-MINDeSEA portal publishes harmonized marine mineral resource information, case studies and maps, and identifies potential areas for responsible resource exploration and extraction, strategic management, and marine spatial planning. This study also provides recommendations for future target areas, studies and standards to be used across Europe as part of this project. 01 27 2023 06 16 2023 289 317 10.1144/SP526-2022-150 1 10.1144/crossmark-policy www.lyellcollection.org true 2022-05-03 2022-09-23 2022-09-26 2023-01-27 European Union's Horizon 2020 731166 GeoE.171.001 https://www.geolsoc.org.uk/publications/lyell-collection/user-license-1-1 https://www.geolsoc.org.uk/publications/lyell-collection/user-license-1-2 10.1144/SP526-2022-150 https://www.lyellcollection.org/doi/10.1144/SP526-2022-150 https://www.lyellcollection.org/doi/pdf/10.1144/SP526-2022-150 https://pubs.geoscienceworld.org/UrlRedirectHandler.ashx?routename=books&chapterdoi=10.1144/SP526-2022-150&request=chapter 10.1007/978-3-642-17220-5_4 Phosphorites on the Sea Floor Baturin G.N. 1982 Baturin, G.N. 1982.
