摘要：Ammonites and dinoflagellate cysts have been applied as the principal means of biostratigraphic dating of the fully cored Blokelv-1 borehole (GEUS 511101), which drilled through 234.80 m of the Upper Jurassic in southern Jameson Land (Figs1–3). It was the first of three core wells drilled by GEUS in 2008–2010 as part of a campaign that aimed to document the petroleum potential of the Upper Jurassic mudstone successions in central East Greenland and North-East Greenland (Bojesen-Koefoed et al. 2009, 2014). Based on outcrop data, these sediments have previously only shown limited source-rock potential (see Bojesen-Koefoed et al. 2018, this volume), yet they are time-equivalent with the prolific source rocks of the UK and Netherlands North Sea (Kimmeridge Clay Formation), the Norwegian North Sea (Draupne Formation) and the Norwegian Sea (Spekk Formation; Brekke et al. 1999, 2001; references in Bojesen-Koefoed et al. 2018, this volume).
