Bardsey Island
Bardsey Island (), known as the legendary "Island of 20,000 Saints", is located off the Llŷn Peninsula in the Wales, Welsh county of Gwynedd. The Welsh language, Welsh name means "The Island in the Currents", while its English name refers to the "Island of the Bards", or possibly the Viking chieftain, "Barda". At in area it is the fourth largest offshore island in Wales, with a population of 11. The north east rises steeply from the sea to a height of at Mynydd Enlli, which is a Marilyn (hill), Marilyn, while the western plain is low and relatively flat cultivated farmland. To the south the island narrows to an isthmus, connecting a peninsula on which the lighthouse stands.Gwynedd Archaeological Trust : ''Bardsey'' Retrieved 16 August 2009 to 2010 Since 1974 it has been included in ...

Daily Post (North Wales)
The ''Daily Post'' is a daily newspaper for the North Wales region of Wales. Its website is branded ''North Wales Live''. The newspaper gained independence from the ''Liverpool Daily Post'' in 2003, which later ceased production in December 2013. It was based on Vale Road, Llandudno Junction, from 2001 to 2017. In May 2017, it moved to its new and current base at Bryn Eirias on Colwyn Bay Colwyn Bay () is a town, Community (Wales), community and seaside resort in Conwy County Borough on the north coast of Wales overlooking the Irish Sea.

North Wales Pilgrims Way
The North Wales Pilgrim's Way () is a long-distance walking route in North Wales, running from near Holywell, Flintshire, Holywell in the east to Bardsey Island () in the west. The first half of the trail takes an inland route, with the second half (from Abergwyngregyn onwards) following the north coast of the Llŷn Peninsula. It measures 133.9 miles (215 km) in length, and was officially launched at Porth y Swnt, Aberdaron on 10 July 2014. Development of the trail started in 2011, and its official opening followed a number of alterations to the original route to suit local concerns. The route, which is marked by waymarker disks, makes use of existing public rights of way, including sections of the Wales Coast Path, and along the way it visits many small stone churches, many dedicated to key Celtic Saints, which can provide shelter and rest along the trail. Whilst, historically, pilgrims would have made their way across North Wales to Bardsey Island, known as the legendary ...

Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Clast
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus,Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-3 chunks, and smaller grains of rock broken off other rocks by physical weathering.Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-5 Geologists use the term clastic to refer to sedimentary rocks and particles in sediment transport, whether in suspension or as bed load, and in sediment deposits. Sedimentary clastic rocks Clastic sedimentary rocks are rocks composed predominantly of broken pieces or ''clasts'' of older weathered and eroded rocks. Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material (matrix) composition, and texture. The classification factors are often useful in determining a sample's environment of deposition. An example of clastic environment would be a river system in which the full range of grains being transported by ...

Gwna Mélange
The Gwna Group (Welsh pronunciation: ; anglicised roughly “GW-nah”) is a late Precambrian (Ediacaran) / Cambrian lithostratigraphic group (a sequence of rock strata) in northwest Wales. The name is derived from the Afon Gwna, a river near Bodorgan on Anglesey where the strata are exposed. This rock sequence is also commonly referred to as the Gwna Mélange. Outcrops These rocks are exposed across various parts of Anglesey and along the northern coast of Llŷn and at Bardsey Island. Lithology and stratigraphy The Group is considered to represent the result of an olistostrome, a giant underwater gravity slide, which occurred probably as a result of tectonic activity at some time after 614 million years ago. It includes clasts, at all sizes from millimetres up to a kilometre or more, of a diverse range of both sedimentary and igneous rocks. Since deposition the group as a whole has been subject to low grade metamorphism. Very large limestone clasts within the mélange which ...

Mélange
In geology, a mélange is a large-scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies. Both tectonic and sedimentary processes can form mélange. Mélange occurrences are associated with thrust faulted terranes in orogenic belts. A mélange is formed in the accretionary wedge above a subduction zone. The ultramafic ophiolite sequences which have been obducted onto continental crust are typically underlain by a mélange. Smaller-scale localized mélanges may also occur in shear or fault zones, where coherent rock has been disrupted and mixed by shearing forces. Large-scale melanges formed in active continental margin settings generally consist of altered oceanic crustal material and blocks of continental slope sediments in a sheared mudstone matrix. The mixi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Precambrian
The Precambrian ( ; or pre-Cambrian, sometimes abbreviated pC, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinized name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.
