Caerfai Group
The Caerfai Group is a Cambrian lithostratigraphy, lithostratigraphic group (stratigraphy), group (a sequence of rock strata) in west Wales. The name is derived from Caerfai Bay on the north coast of St Brides Bay on the Pembrokeshire coast where the stratum, strata are well exposed in coastal cliffs. This rock succession has previously been known variously as the Caerfai Series, Caerfai Formation and Caerfai Beds and largely ascribed to the British regional stratigraphic unit ''Comley Epoch'', though these terms are now obsolete. Outcrops The rock succession is exposed, along the coast south of St Davids and in particular at Caerfai and St Non’s bays to the south of the city where they are seen to overlie Precambrian volcaniclastic rocks of the Pebidian Supergroup. They are exposed again on the west-facing coast of the St Davids peninsula facing Ramsey Island. Further outcrops though less well exposed occur south of Croes-goch and north and east of Newgale and again in the Wolf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and '' lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Caer (; owl, cair or ') is a placename element in Welsh meaning "stronghold", "fortress", or "citadel", roughly equivalent to an Old English suffix (''-ceaster'') now variously written as , , and .Allen, Grant. [Baidu] |
Newgale Formation
Newgale ( cy, Niwgwl) is a village with an almost stretch of beach in the parish of Roch, Pembrokeshire, West Wales. The beach is situated in the Pembrokeshire Coast National Park and on the Pembrokeshire Coast Path and has rugged coastal scenery with the path winding up and down the cliffs. Newgale is one of over 40 Welsh Blue Flag beaches, which means it has the top certification for quality, cleanliness and facilities. Village and beach The beach is backed by a large pebble bank which was created by a major storm on 25 October 1859, and which acts as a sea defence or storm beach; however, it is often breached, and rocks are washed onto the main road. In the January 2014 storms the sea washed the pebble wall across the road and a large wave washed the early evening Richards Bros bus into the adjoining field. Newgale is popular with holiday makers, windsurfers, surfers and canoeists throughout the summer months. There are two caravan parks, a camping site, some shops and a p ...
