The new Scoresby Land Supergroup is now\ncomposed of the Wordie Creek, Pingo Dal, Gipsdalen and Fleming Fjord Groups.\nThis paper only deals with the lithostratigraphy of the late Early-Late Triassic\ncontinental deposits of the latter three groups with emphasis on the vertebratebearing\nFleming Fjord Group. The new Pingo Dal Group consists of three new\nformations, the R\u00f8dstaken, Paradigmabjerg and Klitdal Formations (all elevated\nfrom members), the new Gipsdalen Group consists of three new formations,\nthe Kolledalen, Solfaldsdal (with the new Gr\u00e5klint Member) and Kap Seaforth\nFormations (all elevated from members), and the new Fleming Fjord Group is\nsubdivided into three new formations, the Edderfugledal, Malmros Klint and\n\u00d8rsted Dal Formations (all elevated from members). The Edderfugledal Formation\ncontains two cyclic bedded, lacustrine members, a lowermost Sporfjeld Member\n(elevated from beds), and an uppermost Pingel Dal Member (elevated from beds).\nThe lacustrine red beds of the Malmros Klint Formation are not subdivided. The\nlacustrine and fluvial \u00d8rsted Dal Formation contains three new members. In the\neastern and central part of the basin, the formation is initiated by cyclic bedded,\nred lacustrine mudstones of the Carlsberg Fjord Member (elevated from beds),\nwhile in the northwestern part of the basin the lowermost part of the formation\nis composed of grey fluvial conglomerates and sandstones with subordinate red\nmudstones of the Bjergkronerne Member (elevated from beds). The uppermost part\nof the formations in most of the basin is composed of cyclic bedded, variegated\nlacustrine mudstones and grey to yellowish marlstones of the Tait Bjerg Member\n(elevated from beds). The sediments in the Fleming Fjord Group contain remains\nof a rich and diverse vertebrate fauna including dinosaurs, amphibians, turtles,\naeotosaurs, pterosaurs, phytosaurs and mammaliaforms. Most vertebrate bones\nhave been found in uppermost Malmros Klint Formation, and in the Carlsberg\nFjord and Tait Bjerg Members. The Norian\u2013early Rhaetian, lacustrine Fleming\nFjord Group was deposited at about 41\u00b0 N on the northern part of the supercontinent\nPangaea. Lacustrine sedimentation was controlled by seasonal as well as\nlonger-term (orbital) variation in precipitation. Precipitation was probably brought\nto the basin by southwesterly winds. The lacustrine sediments of the uppermost\nFleming Fjord Group show deposition during increasingly humid conditions\nchanging the lake environment from an ephemeral lake-steppe area to a perennial\nlake. This evolution of lake environment suggests a change from a winter-wet\ntemperate climate to one with precipitation throughout the year.<\/jats:p>","DOI":"10.37570\/bgsd-2020-68-05","type":"journal-article","created":{"date-parts":[[2020,6,7]],"date-time":"2020-06-07T16:31:15Z","timestamp":1591547475000},"page":"95-132","source":"Crossref","is-referenced-by-count":3,"title":["Triassic lithostratigraphy of the Jameson Land Basin (central East\nGreenland), with emphasis on the new Fleming Fjord Group"],"prefix":"10.37570","volume":"68","author":[{"given":"Lars B.","family":"Clemmensen","sequence":"first","affiliation":[{"name":"Department of Geoscience and Natural Resource Management, University of Copenhagen, \u00d8ster Voldgade 10, DK-1350 Copenhagen K, Denmark"}]},{"given":"Dennis W.","family":"Kent","sequence":"additional","affiliation":[{"name":"Lamont - Doherty Earth Observatory, Palisades, NY 10968, USA and Earth and Planetary Sciences, Rutgers University, Picataway, NJ 08854, USA"}]},{"given":"Malte","family":"Mau","sequence":"additional","affiliation":[{"name":"Department of Geoscience and Natural Resource Management, University of Copenhagen, \u00d8ster Voldgade 10, DK-1350 Copenhagen K, Denmark."}]},{"given":"Oct\u00e1vio","family":"Mateus","sequence":"additional","affiliation":[{"name":"GEOBIOTEC, Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa and Museu da Lourinh\u00e3, Portugal."}]},{"given":"Jesper","family":"Mil\u00e0n","sequence":"additional","affiliation":[{"name":"Geomuseum Faxe \u00d8stsj\u00e6llands Museum, \u00d8stervej 2b, 4640 Faxe, Denmark."}]}],"member":"23772","published-online":{"date-parts":[[2020,6,5]]},"container-title":["Bulletin of the Geological Society of Denmark"],"original-title":[],"language":"en","deposited":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T09:51:08Z","timestamp":1595325068000},"score":1,"resource":{"primary":{"URL":"https:\/\/2dgf.dk\/publikationer\/bulletin\/bulletin-volume-68-2020\/#5"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,6,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.37570\/bgsd-2020-68-05","relation":{},"ISSN":["2245-7070"],"issn-type":[{"value":"2245-7070","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,6,5]]}}}
