Widmerpool Gulf
The Widmerpool Gulf is a name given to a sedimentary basin that existed as an area of open water during the Early Carboniferous (Tournaisian Age). It is named after Widmerpool, near Nottingham and was an extension eastwards as far as Lincolnshire, of the North Staffordshire Gulf. It was formed during a rifting event, which began in the Late Devonian, that affected the area between the London-Brabant Massif to the south and the Highland Boundary Fault to the north.〔(Waters, C.N., Browne, M.A.E., Dean, M.T., and Powell, J.H., 2007. Lithostratigraphical framework for Carboniferous successions of Great Britain (Onshore). British Geological Survey Research Report, RR/07/01. 60pp )〕 It has a large normal fault on its southern margin and has the form of a half-graben.〔(Waters, C.N.; Davies, S.J.. 2006 Carboniferous : extensional basins, advancing deltas and coal swamps.

In time, the equatorial swamp forests on its shores were converted into the coalfields of Leicestershire, to the south and Nottinghamshire, to the north.
