The Caban Conglomerate and Ystrad Meurig Grits Formation — nested channels and lobe switching on a mud-dominated latest Ashgill to Llandovery slope-apron, Welsh Basin, UK

  • Chapter
Atlas of Deep Water Environments

Abstract

Throughout much of the Lower Palaeozoic, the Welsh Basin was a small intracratonic basin in which deep-water sediments accumulated (Woodcock 1984a; Soper and Woodcock 1990). It lay on the former microcontinent of Eastern Avalonia, on the south side of the contemporary Iapetus Ocean. To the south and east it was bordered by the Midland Platform, a stable cratonic area, that was periodically emergent or the site for shallow-water, shelf sedimentation. The eastern margin of the basin was defined by the Welsh Borderland Fault System, which comprises three long-lived basement structures, the Tywi, Pontesford and Church Stretton lineaments (Woodcock and Gibbons 1988) (Fig. 26.1a). These structures are manifested today as narrow, linear fold and fault belts.
