Emphasis has been placed on the sandy Utsira and Skade formations. Detailed analyses of foraminiferal and Bolboforma fossil assemblages supported by strontium isotopic data from six exploration and two production wells suggest that the Skade sands were deposited mainly during the Early Miocene whereas the Utsira sands were deposited during the Late Miocene and Early Pliocene. All biostratigraphic data are presented in range charts and have been integrated with wireline log and seismic data. Strontium isotope stratigraphy has been used as an additional dating tool and has proved powerful in the sandy sections. This work also demonstrates a need for an update or modification of the lithostratigraphic nomenclature of the post-Eocene succession in the Norwegian North Sea, and a proposal for a revision is presented. 1.5 1.5 58.75 58.75 1.5 58.75 500.0 1520.0 not specified ECO2 Sub-seabed CO2 Storage: Impact on Marine Ecosystems http://www.eco2-project.eu/ IFM-GEOMAR Leibniz-Institute of Marine Sciences, Kiel University IFM-GEOMAR http://www.geomar.de https://ror.org/02h2x0161 Seventh Framework Programme of the European Commission FP7 https://doi.org/10.13039/100011102 265847 Sub-seabed CO2 Storage: Impact on Marine Ecosystems https://cordis.europa.eu/project/id/265847 Viking_Graben 58.75 1.5 Southern North Sea North Sea 1151 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Site Site site Eidvin Tor Site Stratigraphy Stratigraphy Eidvin Tor Stratigraphy DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Eidvin Tor Depth sed [m] Sample type Samp type Eidvin Tor Samp type Strontium-87/Strontium-86 ratio 87Sr/86Sr strontium-87 87Sr strontium-86 86Sr https://en.wikipedia.org/wiki/Isotopes_of_strontium ratio Eidvin Tor 87Sr/86Sr Age, dated Age dated ka age http://purl.obolibrary.org/obo/PATO_0000011 Time T http://dbpedia.org/resource/Time Eidvin Tor Age dated [ka] Comment Comment Eidvin Tor Comment supplement citable author28934 author60554 award52 event2831314 funder20486 geocode1 geocode1600 geocode1601 inst6 journal12035 license101 param14033 param1570 param1666 param48491 param5506 param7059 pi28934 project4138 ref89373 term1073131 term1073135 term2663825 term29692 term37810 term38263 term40739 term41056 term43863 term43975 term44325 topotype1
