Black Country Geopark
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. Geology The Geopark extends across territory underlain by sedimentary rocks of Silurian, Devonian, Carboniferous, Permian and Triassic age together with some limited outcrops of igneous rocks. Coal, ironstone, limestone, fireclay, brick clay and building stones have all been exploited in the area in the last few centuries. Evidence is also present for the margins of both the Anglian icesheet and the Devensian icesheet. Silurian rocks The oldest rocks which outcrop at the surface within the Geopark are the early Silurian shales and limestones which are seen in a series of faulted and folded inliers between Lye in the south and Ettingshall Park in the north. There is a further area of Silurian rocks exposed between Walsall, Gravelly Hill Intercha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fireclay
Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al2O3·2SiO2·2H2O) with or without free silica." Properties High-grade fire clays can withstand temperatures of 1,775 °C (3,227 °F), but to be referred to as a "fire clay" the material must withstand a minimum temperature of .Minerals Zone, World Mineral Exchange. Retrieved 2011-6-23. Fire clays range from ''s'' to ''plastic fire clays'', but there are ''semi-flint'' and ''semi-plastic'' fire clays as well. Fire clays consist ...

Stratigraphy
Stratigraphy is a branch of geology concerned with the study of rock (geology), rock layers (Stratum, strata) and layering (stratification). It is primarily used in the study of sedimentary rock, sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith (geologist), William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of Stratum, strata or rock layering and the importance ...

Aldridge
Aldridge is an industrial town in the Walsall borough, West Midlands, England. It is historically a village that was part of Staffordshire until 1974. The town is from Brownhills, from Walsall, from Sutton Coldfield and from Lichfield. The town is also the second-largest town in the Walsall Borough (By population after Walsall). History The name "Aldridge" is derived from the Anglo-Saxon ''alr'' or ''alre'' + ''wīc'' meaning 'alder (tree) + village'. Another suggestion is that the name "Aldridge" means "outlying farm among alder-trees", from the Old English ''alor'' and ''wīc''. It was recorded as ''Alrewic'' in the Domesday Book of 1086 when it was valued at 15 shillings and had a population of seven households; the Lord was Robert (d'Oilly) and the tenant-in-chief was William son of Ansculf. The name was recorded as ''Alrewich'' and ''Allerwych'' in the 12th century. Aldridge began as a small agricultural settlement, with farming being the most common occupatio ...

Gravelly Hill Interchange
The Gravelly Hill Interchange, popularly known as Spaghetti Junction, is a road junction in Birmingham, England. It is junction 6 of the M6 motorway where it meets the A38(M) Aston Expressway in the Gravelly Hill area of Birmingham. The interchange was opened on 24 May 1972. Background The asymmetrical junction provides access to and from the A38 (Tyburn Road), A38(M) (Aston Expressway), the A5127 (Lichfield Road/Gravelly Hill), and several unclassified local roads. It covers , serves 18 routes and includes of slip roads, but only of the M6 itself. Across five different levels, it has 559 concrete columns, reaching up to . The engineers had to elevate of motorway to accommodate two railway lines, three canals and two rivers. In 1958, the Ministry of Transport commissioned the engineering firm Sir Owen Williams & Partners to investigate possible routes to connect the M6, the A38(M) and the A38 trunk road.

Lye, West Midlands
Lye or The Lye is an area in the Metropolitan Borough of Dudley, Dudley Metropolitan Borough, in the West Midlands (county), West Midlands county, England, east of Stourbridge and borders with Pedmore and Wollescote. It was formerly a village within the parish of Oldswinford, historically situated within the boundaries of the county of Worcestershire. It used to be famous for the manufacture of nails, anvils, vices, chain, crucibles and firebricks. Lye Waste, adjacent to the original village of Lye, was an area of uncultivated common land but it was settled by people who, by building houses including a fireplace within 24 hours by using mud and clay as the main building materials, acquired Freehold (law), freehold rights as a result of the passing of the Inclosure Acts from 1604 onwards, and it became thickly built upon. The village of Careless Green, now part of Lye but once a separate village immediately to the south-east, was noted for insurance clubs called Stewpony societies ...

Inliers And Outliers (geology)
An inlier is an area of older rocks surrounded by younger rocks. Inliers are typically formed by the erosion of overlying younger rocks to reveal a limited exposure of the older underlying rocks. Faulting or folding may also contribute to the observed outcrop pattern. A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone. The location has long been visited by geology students and experts. Another example from South Wales is the Usk Inlier in Monmouthshire where Silurian age rocks are upfolded amidst Old Red Sandstone rocks of Devonian age. A similar outcrop pattern which results from movement on a thrust fault followed by erosion may be termed a window. Conversely an outlier is an area of younger rock surrounded by older rocks. An outlier is typically formed when sufficient erosion of surrounding rocks has taken place to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fold (geology)
In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as ''fold trains''). Synsedimentary folds are those formed during sedimentary deposition. Folds form under varied conditions of stress, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (''fault bend fold''), at the tip of a propagating fault (''fault propagation fold''), by differential compaction or due to ...
