The LR is thought to have been separated from the northern Barents-Kara Sea passive continental margin by continental rifting at about 53-56 Ma and the subsequent formation of the oceanic crust in the Eurasia Basin. Following the nomenclature of this volume, the sedimentary succession of the LR and nearby area forms a composite tectono-sedimentary element containing an assemblage of the following main tectono-sedimentary elements (TSEs): (1) an undefined group of pre-rift TSEs mostly composed of Mesozoic and poorly known Paleozoic successions, (2) the Cretaceous-Paleocene syn-rift TSE, and (3) the Eocene-Holocene post-rift TSE. The age of the LR's folded and metamorphosed basement can be inferred based on correlations to basement units of the northern Eurasian passive continental margin which may include a variety of geological structures formed during Timanian, Caledonian, late Paleozoic and Mesozoic orogenic events. The pre-rift TSE includes the oldest and most poorly known offshore sedimentary succession in the Arctic region. The lithostratigraphic units of these basins were mainly characterized by a handful samples collected at the seafloor, and by correlation with better known stratigraphy of the conjugate continental margin. The syn-rift TSE of Cretaceous-Paleocene age has been defined based on seismic data and samples of sedimentary rocks recovered during the Arctic Coring Expedition (ACEX), as well as from seismic facies correlation between the LR and Podvodnikov-Makarov, Laptev and East Siberian Sea basins. The post-rift Cenozoic sedimentary record was documented by the ACEX well in the central part of the LR.","PeriodicalId":191175,"journal":{"name":"Geological Society, London, Memoirs","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131814885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The East Greenland Prograded Margin Tectono-Sedimentary Element (EGPM-TSE) is made of six segments with their basal part deferring from Maastrichtian to Miocene in age. The variation reflects the different timing in transition from syn- to post-rift, controlled by the lateral migration of rifting and diachronic continental break-up in northern North Atlantic. The post-rift history can be subdivided into a pre-break-up Maastrichtian-Paleocene post-rift phase developed entirely offshore NE Greenland, an earliest Eocene to Miocene syn- to post-break-up phase developed in the wake of progressive continental rupture. Finally, the cTSE started to develop as a unified body since the Miocene after the complete separation of Greenland from Eurasia and the Jan Mayen microcontinent. The Greenland Sea Oceanic Tectonic-Sedimentary Element formed since the earliest Eocene commencement of seafloor spreading. The structural and depositional outline of the EGPMGCO-CTSE depicts its tectonic history, but also reflects phases of volcanism, denudation and intensified icehouse conditions since the middle Miocene triggered by the Fram Strait opening and the East Greenland uplift. The first major northern hemisphere glaciations started in NE Greenland. Glaciations expanded southwards during the late Miocene as the Denmark Strait was transgressed and cold surface water from the high arctic started flowing along SE Greenland cooling the region. The petroleum potential of the EGPM-TSE is conceivably modest, but a potential exists locally offshore the northern NE Greenland where hydrocarbons sourced mainly from the Jurassic-Cretaceous section may have charged structures cored by Maastrichtian to Eocene sandstone reservoirs sealed by overlying marine mudstones.","PeriodicalId":191175,"journal":{"name":"Geological Society, London, Memoirs","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121905694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The syn-rift TSE is the most prospective part of the margin and hydrocarbon shows have been documented in some wells and offshore seeps studies.

The sedimentary succession ranges from the Late Paleozoic throughout most of the Mesozoic. Terrestrial sediments of the Billefjorden Group (Famennian - Visean) are likely present and overlain by evaporites and carbonates of the Gipsdalen Group (Serpukhovian - Late Artinskian). Most of the Triassic is dominated by deposits from a huge prograding deltaic system building out from the south, southeast and east, becoming successively younger towards northwest. The system was primarily sourced from the Urals, but also partly from mainland Norway and most likely from Taimyr. The progradation started in the Late Permian and reached Svalbard in the Early Carnian. The entire delta system was flooded during the regional Early Norian transgression, resulting in deposition of marine shales of the Flatsalen Formation (Svalbard) and the time equivalent Akkar Member of the Fruholmen Formation (Barents Sea). The Cretaceous and the Paleogene are comprehensively and completely, respectively, eroded. During Pliocene - Pleistocene, the entire Barents shelf was a site of repeated glaciations resulting in extensive erosion. Hydrocarbon source rocks occur at several stratigraphic levels from Carboniferous to Jurassic, of which the most important is assumed the Lower - Middle Triassic Steinkobbe / Botneheia Formation. The Upper Jurassic Hekkingen Formation, where present, is likely immature in the whole area. Potential reservoir rocks are Permian carbonates and siliciclastic rocks of Carboniferous and Mesozoic age.","PeriodicalId":191175,"journal":{"name":"Geological Society, London, Memoirs","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128364682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, there are inconsistencies in unit definition and nomenclature changes across country sector boundaries which obscure the recognition of regional stratigraphic patterns that exist across the region.\u0000 To aid clarity and to overcome some issues of definition, some revisions are made to the existing lithostratigraphic schemes. Several informal lithostratigraphic units are described, a number of unit definitions are revised, and various formerly informal units are formalized (Buzzard Sandstone Member, Ettrick Sandstone Member, Galley Sandstone Member). It is recommended that use of the Heno Formation in offshore Denmark is discontinued. In addition, four new lithostratigraphic member terms are introduced (Home Sandstone Member, North Ettrick Sandstone Member, Gyda Sandstone Member, Tambar Sandstone Member).
