摘要：The Blokelv-1 fully cored borehole was drilled with almost full recovery to a total depth of 234 m in southern Jameson Land, East Greenland within the central part of the Jameson Land Basin (Fig. 1; Bjerager et al. 2018a, this volume). Laminated mudstones dominate the cored succession of Jurassic sediments referred to the Hareelv Formation. Sandstone layers make up 36% of the core and are generally 1–7 m thick, and heterolithic bedded intervals make up 11% of the cored succession (Fig. 2; Bjerager et al. 2018a, this volume). Good reservoir quality is present in most of the sandstones, and the interbedded mudstones constitute rich gas/oil-prone source rocks (Boje- sen-Koefoed et al. 2018, this volume). Thus, the Blokelv-1 succession may act as an analogue for similar sandstone– mudstone complexes in the North Atlantic region.
