The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica/Laurussia. In Britain it is a lithostratigraphic unit to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain.
Bromyard is a town in Herefordshire, England, in the valley of the River Frome. It lies near the county border with Worcestershire on the A44 between Leominster and Worcester. Bromyard has a number of traditional half-timbered buildings, including some of the pubs, and the parish church is Norman. For centuries, there was a thriving livestock market. The town is twinned with Athis-de-l'Orne, Normandy.
Clun Forest is a remote, rural area of open pastures, moorland and mixed deciduous/coniferous woodland in the southwest part of the English county of Shropshire and also just over the border into Powys, Wales.
The Black Mountains are a group of hills spread across parts of Powys and Monmouthshire in southeast Wales, and extending across the England–Wales border into Herefordshire. They are the easternmost of the four ranges of hills that comprise the Brecon Beacons National Park, and are frequently confused with the westernmost, which is known as the Black Mountain. The Black Mountains may be roughly defined as those hills contained within a triangle defined by the towns of Abergavenny in the southeast, Hay-on-Wye in the north and the village of Llangors in the west. Other gateway towns to the Black Mountains include Talgarth and Crickhowell. The range of hills is well known to walkers and ramblers for the ease of access and views from the many ridge trails, such as that on the Black Hill (Herefordshire) at the eastern edge of the massif. The range includes the highest public road in Wales at Gospel Pass, and the highest point in southern England at Black Mountain.
Leominster was a parliamentary constituency represented until 1707 in the House of Commons of England, then until 1801 in that of Great Britain, and finally until 2010, when it disappeared in boundary changes, in the Parliament of the United Kingdom.
The geology of Shropshire is very diverse with a large number of periods being represented at outcrop. The bedrock consists principally of sedimentary rocks of Palaeozoic and Mesozoic age, surrounding restricted areas of Precambrian metasedimentary and metavolcanic rocks. The county hosts in its Quaternary deposits and landforms, a significant record of recent glaciation. The exploitation of the Coal Measures and other Carboniferous age strata in the Ironbridge area made it one of the birthplaces of the Industrial Revolution. There is also a large amount of mineral wealth in the county, including lead and baryte. Quarrying is still active, with limestone for cement manufacture and concrete aggregate, sandstone, greywacke and dolerite for road aggregate, and sand and gravel for aggregate and drainage filters. Groundwater is an equally important economic resource.
Bishop's Frome is a village and civil parish in eastern Herefordshire, England. The village is 11 miles (18 km) north-east of the city and county town of Hereford, 8 miles (13 km) west of Malvern and 4 miles (6 km) south of Bromyard. The civil parish includes the hamlets of Halmond's Frome and Fromes Hill.
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.
The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian to the Jurassic are represented at outcrop, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains.
The Geology of Yorkshire in northern England shows a very close relationship between the major topographical areas and the geological period in which their rocks were formed. The rocks of the Pennine chain of hills in the west are of Carboniferous origin whilst those of the central vale are Permo-Triassic. The North York Moors in the north-east of the county are Jurassic in age while the Yorkshire Wolds to the south east are Cretaceous chalk uplands. The plain of Holderness and the Humberhead levels both owe their present form to the Quaternary ice ages. The strata become gradually younger from west to east.
The Bishop's Frome Limestone is a rock unit within the Raglan Mudstone Formation of the Old Red Sandstone occurring in the border region between England and South Wales. This limestone is a calcrete, that is to say it originated as a soil during a break in deposition rather than being an original marine deposit. It is perhaps the most significant of all of the calcretes which occur within the uppermost Silurian and lower Devonian sequence of rocks which constitute the Old Red Sandstone of the Anglo-Welsh Basin. It defines the boundary within the basin between the Silurian and the Devonian periods. The rock was formerly known as the Psammosteus Limestone after a characteristic fossil fish recorded from it; Psammosteus anglicus. The fossil remains were subsequently shown to have been wrongly identified and belong in fact to Traquairaspis symondsi. Its modern name derives from the Herefordshire village of Bishop's Frome. Its thickness is variable ranging from 2m up to 8m.
The geology of Monmouthshire in southeast Wales largely consists of a thick series of sedimentary rocks of different types originating in the Silurian, Devonian, Carboniferous, Triassic and Jurassic periods.
This article describes the geology of the Brecon Beacons National Park in mid/south Wales. The area gained national park status in 1957 with the designated area of 1,344 km2 (519 sq mi) including mountain massifs to both the east and west of the Brecon Beacons proper. The geology of the national park consists of a thick succession of sedimentary rocks laid down from the late Ordovician through the Silurian and Devonian to the late Carboniferous period. The rock sequence most closely associated with the park is the Old Red Sandstone from which most of its mountains are formed. The older parts of the succession, in the northwest, were folded and faulted during the Caledonian orogeny. Further faulting and folding, particularly in the south of the park is associated with the Variscan orogeny.
Castle Frome is a village and civil parish in the county of Herefordshire, England, and is 10 miles (16 km) north-east from the city and county town of Hereford. The closest large town is the market town of Bromyard, 5 miles (8 km) to the north. The Norman font in Castle Frome church is "one of the outstanding works of the Herefordshire school".
The geology of Snowdonia National Park in North Wales is dominated by sedimentary and volcanic rocks from the Cambrian and Ordovician periods with intrusions of Ordovician and Silurian age. There are Silurian and Cenozoic sedimentary rocks on the park's margins. The succession was intensely faulted and folded during the Caledonian Orogeny. The region was uplifted as the North Atlantic Ocean opened during the Cenozoic. The current mountainous landscape arises from repeated glaciations during the Quaternary period.
The Black Country UNESCO Global Geopark is a geopark in the Black Country, a part of the West Midlands region of England. Having previously been an ‘aspiring Geopark’, it was awarded UNESCO Global Geopark status on 10 July 2020.
The bedrock geology of Ceredigion in west Wales consists wholly of a considerable thickness of Ordovician and Silurian age sedimentary rocks of marine origin. Unconsolidated deposits of Quaternary age include a widespread cover of glacial till, valley floor alluvium and scattered peat deposits in both upland and lowland settings.
