Barns Batch Spinney (grid reference ST557659 ) is a 0.06-hectare geological Site of Special Scientific Interest near the village of Dundry, North Somerset, notified in 1987.

The English Nature citation says that Barns Batch Spinney is important because of the exposures which it provides of the lower part of the classic Inferior Oolite limestone sequence of the Dundry area. It shows rocks lying stratigraphically below the Middle and Upper Inferior Oolite Limestones seen at Dundry Main Road South Quarry. [1]

The geology at this site provides a section spanning the division of the Middle Jurassic known as the Aalenian and Bajocian Stages and a sequence of rocks placed in the subdivision known as the discites zone, named after the characteristic fossil ammonite Hyperlioceras discites. This is one of the thickest sequences in Britain and may be used as the basis for defining these new subzones. [1]

Dundry Hill

Dundry Hill is immediately south of Bristol, England: it includes farmland, a small number of houses and a church. It stretches east–west for some two miles. Most of the hill is within the district of North Somerset. At the hill's eastern end the southern slopes are within Bath and North East Somerset, and the northern slopes are within the city and county of Bristol, including the highest point in that county.

Lincoln 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.

Geology of Somerset

Somerset is a rural county in the southwest of England, covering 4,171 square kilometres (1,610 sq mi). It is bounded on the north-west by the Bristol Channel, on the north by Bristol and Gloucestershire, on the north-east by Wiltshire, on the south-east by Dorset, and on the south west and west by Devon. It has broad central plains with several ranges of low hills. The landscape divides into four main geological sections from the Silurian through the Devonian and Carboniferous to the Permian which influence the landscape, together with water-related features.

Chew Valley Human settlement in England

The Chew Valley is an affluent area in North Somerset, England, named after the River Chew, which rises at Chewton Mendip, and joins the River Avon at Keynsham. Technically, the area of the valley is bounded by the water catchment area of the Chew and its tributaries; however, the name Chew Valley is often used less formally to cover other nearby areas, for example, Blagdon Lake and its environs, which by a stricter definition are part of the Yeo Valley. The valley is an area of rich arable and dairy farmland, interspersed with a number of villages.

Frogden Quarry is a 0.2 hectare geological Site of Special Scientific Interest in Dorset, England, notified in 1954, by geologist Benjamin Starr. It exposes rocks of the Inferior Oolite, of Aalenian and Bajocian age. The sequence largely consists of limestone, with some marl and siltstone.

Geology of Gloucestershire

Gloucestershire is one of the most geologically and scenically diverse counties in England, with rocks from the Precambrian through to the Jurassic represented. These varying rock-types are responsible for the three major areas of the county, each with its own distinctive scenery and land-use - the Forest of Dean in the west, bordering Wales, the Cotswolds in the east, and in between, the Severn Vale.

The Lias Group or Lias is a lithostratigraphic unit 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.

Inferior Oolite

The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic. The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group in southern and eastern England. It has been variously known in the past as the Under Oolite, the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group.

Great Estuarine Group

The Great Estuarine Group is a sequence of rocks which outcrop around the coast of the West Highlands of Scotland. Laid down in the Hebrides Basin during the middle Jurassic, they are the rough time equivalent of the Inferior and Great Oolite Groups found in southern England.

The site is listed in the ‘Stroud District’ Local Plan, adopted November 2005, Appendix 6 as an SSSI and a Regionally Important Geological Site (RIGS). The Common is also a Special Area of Conservation (SAC) under the EU Habitats Directive

The geology of Rutland in eastern England largely consists of sedimentary rocks of Jurassic age which dip gently eastwards.

The geology of Lincolnshire in eastern England largely consists of an easterly dipping succession of Mesozoic age sedimentary rocks, obscured across large parts of the county by unconsolidated deposits dating from the last few hundred thousand years of the present Quaternary Period.

Finedon Top Lodge Quarry

Finedon Top Lodge Quarry, also known as Finedon Gullet is a 0.9 hectare geological Site of Special Scientific Interest east of Wellingborough in Northamptonshire. It is a Geological Conservation Review site revealing a sequence of middle Jurassic limestones, sandstones and ironstones, and is the type section for a sequence of sedimentary rocks known as the 'Wellingborough Member'. It was created by quarrying for the underlying ironstone for use at Wellingborough and Corby Steelworks; the ore was transported by the 1,000 mm gauge Wellingborough Tramway.
