Craig Y Forwyn, Conwy
Craig y Forwyn (meaning "Maiden's Crag" in English) is a crag in Conwy County Borough, Wales, located less than a mile south of Llanddulas, near the village of Rhyd y Foel. The cliff is composed of carboniferous limestone and is of interest to geologists as a source of fossils and to rock climbers as a fine cliff with many interesting climbing routes. Rock climbing Craig y Forwyn reaches a height of , and rock climbers have identified and rated more than 160 routes for ascending it. The rapidity with which the rock dries makes the cliff a useful climbing venue after rain has fallen. Location The cliff lies on the west bank of the Afon Dulas, which reaches the sea at Llanddulas, and is slightly inland of the belt of carboniferous limestone that runs along the coast from Great Ormes Head to Point of Ayr, about three miles west of Abergele. The Dulas passes through a gap in the limestone belt, the strata of which dip from the north or northeast. This band of limestone is les ...

Abergele
Abergele (; ; ) is a market town and community, situated on the north coast of Wales between the holiday resorts of Colwyn Bay and Rhyl, in Conwy County Borough and in the historic county of Denbighshire. Its northern suburb of Pensarn lies on the Irish Sea coast. Abergele and Pensarn railway station serves both resorts. Abergele is often overlooked due to the popularity of towns in nearby Rhyl, Prestatyn, Colwyn Bay, Llandudno and Conwy. Only 46.5% of the population was born in Wales as of the 2011 census. Etymology The meaning of the name can be deduced by being the Welsh word for estuary, river mouth or confluence and the name of the river which flows through the town. is a dialectal form of , which means spear, describing the action of the river cutting through the land. It has also been suggested this river is named because its waters flash brightly. Abergele is often mispronounced as ah-bear-geh-lee by non-native Welsh speakers. Geography The town itself lies ...

Bivalvia
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estim ... that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into Ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they a ...

Encrinite
Encrinites are a type of grain-supported bioclastic sedimentary rock in which all or most of the grains are crinoid ossicles. In older literature, the word is sometimes used to refer to individual fossil crinoids, but this usage is obsolete. Distribution Encrinites form in areas where disaggregated crinoid skeletal debris becomes concentrated, typically shallow warm euhaline seas. They are therefore very common in the Paleozoic rock record of North America and Eurasia, particularly during the Silurian through Early Devonian and the Early Mississippian age, when high sea levels created widespread epeiric seas. Some encrinites are also known from the Jurassic The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya.

Lepidodendron
''Lepidodendron'' is an extinct genus of primitive vascular plants belonging to the family Lepidodendraceae, part of a group of Lycopodiopsida known as scale trees or arborescent lycophytes, related to Isoetes, quillworts and Lycopodiopsida, lycopsids (club mosses). They were part of the coal forest flora. They sometimes reached heights of , and the trunks were often over in diameter. They thrived during the Carboniferous Period (358.9 to 298.9 million years ago). Sometimes erroneously called "giant club mosses", the genus was actually more closely related to modern quillworts than to modern club mosses. Within the form classification system used within paleobotany, ''Lepidodendron'' is both used for the whole plant as well as specifically the stems and leaves. Etymology The name ''Lepidodendron'' comes from the Greek language, Greek wikt:λεπίς, λεπίς ', scale, and wikt:δένδρον, δένδρον ''dendron'', tree. Growth During the early stages of growth, ''L ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point Of Ayr
:''There are two other similarly named points in the British Isles: Point of Ayre, Isle of Man and Point of Ayre, Orkney, Scotland.'' Point of Ayr ( cy, Y Parlwr Du) is the northernmost point of mainland Wales. It is situated immediately to the north of Talacre in Flintshire, at the mouth of the Dee estuary. It is to the southwest of the Liverpool Bay area of the Irish Sea. It is the site of a RSPB (Royal Society for the Protection of Birds) nature reserve RSPB Dee Estuary Point of Ayr, and is part of Gronant and Talacre Dunes Site of Special Scientific Interest. Coal For many years a colliery operated at Point of Ayr at the northern extremity of the Flintshire Coalfield; it was one of the last remaining operational deep mines in Wales. The first trial borings took place in 1865, under the direction of Lord Mostyn, owner of Mostyn Colliery, a few miles away. The borings seemed successful, and the Prestatyn Coal Company was formed to commence operations proper, however the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ormes Head
The Great Orme ( cy, Y Gogarth) is a limestone headland on the north coast of Wales, north-west of the town of Llandudno. Referred to as ''Cyngreawdr Fynydd'' by the 12th-century poet Gwalchmai ap Meilyr, its English name derives from the Old Norse word for sea serpent. The Little Orme, a smaller but very similar limestone headland, is on the eastern side of Llandudno Bay. Toponym Both the Great and Little Ormes have been etymologically linked to the Old Norse words ''urm'' or ''orm'' that mean sea serpent (English ''worm'' is a cognate). One explanation is that the Great Orme is the head, with its body being the land between the Great and Little Ormes, whilst another, possibly more likely, is that the shape of the Great Orme viewed as one enters the isthmus of Llandudno from the southeast landward end resembles a giant sleeping creature. The Vikings left no written texts of their time in North Wales although they certainly raided the area. They did not find any permanent set ...
