It comprises a condensed, predominantly shallow marine succession characterized by long hiatuses and erosional reworking with several horizons of extraformational pebble grade conglomerate.<\/jats:p>\n          <jats:p>Six distinct facies associations describe sedimentological environments ranging from transgressive, tidal, fluvial and regressive shoreface. Deposits are interpreted and correlated within three sequence stratigraphic units (SI to SIII) which reflect variations in relative sea-level during an overall transgression of the basin. Interpreted depositional systems show subtle variations in petrographic character, but provenance analyses reveal different sedimentary sources. Thirteen core samples distributed geographically and stratigraphically were analysed for detrital zircon U-Pb geochronology. Data show that the Southwestern Barents Sea Basin (SWBSB) was dominated by mixing of reworked material and coarse grained sediment supply from extrabasinal source areas including a Caledonian provenance in the southwest and a Fennoscandian provenance to the southeast. Intra-basinal erosion of underlying strata with Triassic zircon grains dominate in northern parts of the basin.<\/jats:p>\n          <jats:p content-type=\"supplementary-material\">\n            <jats:bold>Supplementary material<\/jats:bold>\n            <jats:bold>:<\/jats:bold>\n            Supporting information relating to the analysis of different dataset and the interpretations presented in the paper are available at\n            <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/doi.org\/10.6084\/m9.figshare.c.3841282\">https:\/\/doi.org\/10.6084\/m9.figshare.c.3841282<\/jats:ext-link>\n            .\n          <\/jats:p>","DOI":"10.1144\/jgs2017-024","type":"journal-article","created":{"date-parts":[[2017,8,11]],"date-time":"2017-08-11T00:40:24Z","timestamp":1502412024000},"page":"130-145","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["Depositional history of a condensed shallow marine reservoir succession: stratigraphy and detrital zircon geochronology of the Jurassic St\u00f8 Formation, Barents Sea"],"prefix":"10.1144","volume":"175","author":[{"given":"Tore Grane","family":"Klausen","sequence":"first","affiliation":[{"name":"Department of Earth Science, University of Bergen, All\u00e9gaten 41, Bergen 5007, Norway"}]},{"given":"Reidar","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Tullow Oil plc, Tordenskioldsgate 6B, Oslo 0160, Norway"},{"name":"Present address: Arcadia Research, Nordraaks gate 10, Oslo 0260, Norway"}]},{"given":"Ji\u0159\u00ed","family":"Sl\u00e1ma","sequence":"additional","affiliation":[{"name":"Department of Earth Science, University of Bergen, All\u00e9gaten 41, Bergen 5007, Norway"},{"name":"Present address: Institute of Geology CAS, v.v.i., Rozvojov\u00e1 269, Prague 6 165 00, Czech Republic"}]},{"given":"Snorre","family":"Olaussen","sequence":"additional","affiliation":[{"name":"The University Centre in Svalbard (UNIS), Longyearbyen 5007, Norway"}]},{"given":"Bjarte","family":"Rismyhr","sequence":"additional","affiliation":[{"name":"Department of Earth Science, University of Bergen, All\u00e9gaten 41, Bergen 5007, Norway"},{"name":"The University Centre in Svalbard (UNIS), Longyearbyen 5007, Norway"}]},{"given":"William","family":"Helland-Hansen","sequence":"additional","affiliation":[{"name":"Department of Earth Science, University of Bergen, All\u00e9gaten 41, Bergen 5007, Norway"}]}],"member":"1881","published-online":{"date-parts":[[2017,8,10]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpetgeo.2013.11.001"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1144\/SP390.29"},{"key":"e_1_3_3_4_1","first-page":"1","article-title":"Depositional history and fauna of a Jurassic phosphorite conglomerate (the Brentskardhaugen Bed) in Spitsbergen","volume":"183","author":"Backstrom S.A.","year":"1985","unstructured":"Backstrom, S.A. & Nagy, J. 1985.
