Fig. 1. Central North Sea location and distribution of Triassic basins. (A) General North Sea location map.
(B) Distribution of Triassic basin-fills across the North Sea region (based on Goldsmith et al ., 2003 and Geluk, 2005).
Erosional gaps within the Triassic basin distribution mark the positions of footwall unconformities which trace
the overprint of the cross-cutting Jurassic rift system. (C) Location of wells referred to in the text. (D) Gross
palaeogeographic setting of the central North Sea (after McKie & Shannon, 2011) in relation to the Southern Permian
Basin and the margin of the Tethys Sea. The map broadly corresponds to the Late Anisian when Tethyan flooding of
the Southern Permian Basin created the Muschelkalk seaway adjacent to the central North Sea. Marine access to the
Southern Permian Basin was via restricted straits which dissected the chain of massifs marking the remnants of the
Variscan mountains.
