Trent Cliff
The Lincoln Cliff or Lincoln Edge is a portion of a major escarpment that runs north–south through Lindsey and Kesteven in central Lincolnshire and is a prominent landscape feature in a generally flat portion of the county. Towards its northern end, near Scunthorpe, it is sometimes referred to as the Trent Cliff. The name preserves an obsolete sense of the word "cliff", which could historically refer to a hillside as well as a precipitous rock face. Description The scarp is formed by resistant Jurassic age rocks, principally the Lincolnshire Limestone Formation, and is remarkable for its length and straightness. However it is modest in height, rising about 50 metres or less above the surrounding landscape. It runs for over 50 miles from the Leicestershire border near Grantham to the Humber Estuary, and is broken only twice by river gaps at Ancaster and Lincoln, through which the rivers Slea and Witham respectively flow. To the west of the Cliff north of Lincoln lies the Rive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jurassic Way
The Jurassic Way is a designated and signed long-distance footpath that connects the Oxfordshire town of Banbury with the Lincolnshire town of Stamford in England. It largely follows an ancient ridgeway traversing Britain; most of its route is in Northamptonshire on the Jurassic limestone ridge in the north of that county. The trail goes near the Oxford and Grand Union canals, past the Great Central Railway's Catesby Tunnel and viaduct, the River Welland, the 82-arch viaduct at Harringworth, and Rockingham Castle. It connects with these long-distance footpaths: *Grand Union Canal Walk, *Hereward Way, *Macmillan Ways, *Midshires Way, *Oxford Canal Walk. The |
Marlstone Rock Formation
The Marlstone Rock Formation is a geological formation in England. It dates to the Early Jurassic, it consists of "Sandy, shell-fragmental and ooidal ferruginous limestone interbedded with ferruginous calcareous sandstone, and generally subordinate ferruginous mudstone beds", with ironstone.

Lias Group
The Lias Group or Lias is a lithostratigraphic unit (a sequence of rock strata) found in a large area of western Europe, including the British Isles, the North Sea, the Low Countries and the north of Germany. It consists of marine limestones, shales, marls and clays. ''Lias'' is a Middle English term for hard limestone, used in this specific sense by geologists since 1833. In the past, geologists used ''Lias'' not only for the sequence of rock layers, but also for the timespan during which they were formed. It was thus an alternative name for the Early Jurassic epoch of the geologic timescale. It is now more specifically known that the Lias is Rhaetian to Toarcian in age (over a period of 20 million years between ) and thus also includes a part of the Triassic. The use of the name "Lias" for a unit of time is therefore slowly disappearing. Subdivisions In southern England, the Lias Group is often divided into Lower, Middle and Upper subgroups. In Southern England the Lias is d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northampton Sand Formation
The Northampton Sand Formation, sometimes called the Northamptonshire Sand, is a Middle Jurassic geological formation which is placed within the Inferior Oolite Group. It was formerly worked extensively in Northamptonshire for its ironstone. The Northampton Sand Formation constitutes the lowest part of the Inferior Oolite Group and lies on the upper Lias clay. It attains a maximum thickness of up to to the north and west of Northampton where it lies in a subterranean basin. In the south, it fades out around Towcester. Northward from the edge of the basin in the upper Lias, under Northampton, it lies progressively lower beneath the Jurassic Lincolnshire limestones. A little to the north of Corby Glen () it is at about from the surface. It fades out under north Lincolnshire as the strata rise towards the Market Weighton Axis. The formation to dates to the Aalenian, and predominantly consists of sandy ironstone, which when freshly exposed is greenish-grey in colour, which weath ...
