The rocks comprising this important area were laid down during the later Carboniferous. This sedimentary succession includes a sequence with a thickness of more than 1,800 m (5,906 ft) in the west. The coal measures were laid down on a low-lying waterlogged plain with peat mires immediately south of an ancient and persistent geological feature ...
Rocks originating in the Carboniferous Period underlie the uplands of eastern and north Lancashire. Listed in order of succession i.e. lowermost/oldest first, they comprise the various limestones, mudstones, siltstones and sandstones of the Bowland High Group and Trawden Limestone Group, Craven Group, Millstone Grit Group, Pennine Coal Measures Group and Warwickshire Group.
Triassic rocks provided the Radyr stone and also the Quarella stone which was worked at Bridgend. [10] Sutton Stone from South Wales' Jurassic outcrop is a highly regarded limestone freestone that has been used in construction throughout the Vale of Glamorgan, it was also shipped over the Bristol Channel to North Devon and North Cornwall which ...
Pembrokeshire's bedrock geology is largely formed from a sequence of sedimentary and igneous rocks originating during the late Precambrian (Neoproterozoic era) and the Palaeozoic era, namely the Ediacaran, Cambrian, Ordovician, Silurian, Devonian and Carboniferous periods, i.e. between 635 and 299 Ma (million years ago). The older rocks in the ...
The geology of the Peak District National Park in England is dominated by a thick succession of faulted and folded sedimentary rocks of Carboniferous age. The Peak District is often divided into a southerly White Peak where Carboniferous Limestone outcrops and a northerly Dark Peak where the overlying succession of sandstones and mudstones dominate the landscape.
The Carboniferous Period saw the Eastern Highlands of Australia form as a result of its collision with what are now parts of South America (e.g. the Sierra de Cordoba) and New Zealand. At the time they were formed they are believed to have been as high as any mountains on the planet today, but they have been almost completely eroded in the 280 ...
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.
In the early Palaeogene period between 63 and 52 million years ago, the last igneous rocks in England were formed. The granite Lundy Island in the Bristol Channel dates from this period. The Alpine Orogeny that took place from about 50 million years ago was responsible for the shaping of the London Basin syncline and the Weald anticline to the ...
