“…An outline of the lithology and distribution of much of the Permian marine sequence at outcrop in north-east England was given by Sedgwick (1829) and details have been added by the authors of Geological Survey Memoirs and many other workers (see individual site accounts for full references); more recent syntheses are by the writer (Smith, 1970a(Smith, , 1974a(Smith, , b, 1980a(Smith, , b, 1992, Pettigrew (1980), Kaldi (1980Kaldi ( , 1986a, Harwood (1981Harwood ( , 1989, Aplin (1985), Goodall (1987) and Hollingworth (1987). Data from outcrop and boreholes are now sufficient for a lateral succession of facies belts to be recognized in three of the main carbonate rock units and for palaeogeographical maps of these to be attempted [see Kaldi (1980Kaldi ( , 1986a and Harwood (1981Harwood ( , 1989 for parts of the sequence in the Yorkshire Province and Smith (1989) for the full sequence in the Durham and Yorkshire provinces].…”

“…It is interpreted as marking the site of an offshore field of high-energy subaqueous dunes (Smith, 1968(Smith, , 1970b, sandwaves (Kaldi, 1980(Kaldi, , 1986a or grainstone barriers (Harwood, 1981(Harwood, , 1989, and separates a shallow protected shelf or lagoon to the west from a deeper-water open marine outer shelf to the east. The sedimentology and diagenesis of these rocks was investigated in detail by Kaldi (1980Kaldi ( , 1986a and their mineralization by Harwood (1981Harwood ( , 1986. By analysis of the trends of the prevalent large-scale cross-stratification, Kaldi showed that the sandwaves were constructed mainly by currents from the north-east (i.e.…”

The change of style from parallel-bedded at the base to coarsely cross-stratified above, points to a rapid deepening of the sea following the inferred peritidal phase of the Hampole Beds (Smith, 1974a(Smith, , b, 1979Kaldi, 1980Kaldi, , 1986aHarwood, 1981Harwood, , 1989. oblique to roughly normal to the inferred contemporary shoreline) with occasional storm currents from the south-east.…”

Permian strata in the British Isles crop out mainly in northern and central England but are extensive in the subsurface both on land and in several adjoining offshore areas. Their base is defined as in Smith et al. (1974) and their top is within red beds, overlying the Zechstein evaporites.We emphasize that both the base and the top of the nominally Permian rocks lie in continental strata almost devoid of stratigraphically useful fossils and that, accordingly, these boundaries are only doubtfully correlated with internationally acceptable biostratigraphic standards.Subdivision of British Permian strata into Lower and Upper series follows the traditional view summarized by Smith et al. (1974). The junction between the series is taken at the incoming of marine strata in northern England and adjoining offshore areas, and at approximately equivalent levels in continuous continental sequences elsewhere; recent limited palynological studies suggest that the early Permian-late Permian transition adopted here and in most of northwest Europe may be mid or late Kazanian or even Tatarian in age which is somewhat younger than the base-Kazanian/Ufimian position taken in more continuous marine sequences.There has been no comprehensive revision of the stratigraphy and nomenclature of early Permian strata in and around the British Isles since the work of Smith et al. (1974) and Rhys (1974), but these aspects of the early Permian continental deposits of several cuvettes and inland drainage basins in southwest Scotland were reviewed by Brookfield (1978) and the age of continental deposits in the Elgin area was reconsidered

SUMMARY All available information has been used in the preparation of a series of palaeogeographical maps showing the evolution of north-east England at the end of the early Permian and at intervals throughout the late Permian. Most of the area initially lay near the western fringe of the Southern North Sea tropical desert basin, much of which was flooded at the beginning of the late Permian so as to create the epicontinental Zechstein Sea. With continually oscillating relative sea levels and episodic differential subsidence, contemporary coastlines fluctuated widely whilst successive progradational carbonate shelves were constructed in the first two of four main cyclic sequences; the deposition of thick salt at the end of the second main cycle almost filled the basin, eliminating most of the earlier depositional topography and ensuring that carbonates and evaporites of the third and fourth cycles were formed in a less diverse range of coastal plain to shallow marine environments.
