A variety of igneous rocks intrude the Dalradian sequence, including dykes, sills and plutons. Along the Highland Boundary Fault is a zone of metamorphosed rocks grouped as the Highland Border Complex and dated to the Cambrian and Ordovician periods. There are outliers of Carboniferous age rocks to the east and west of Loch Lomond.
The sediments were uplifted and faulted within the Variscan Orogeny, with the land now occupied by East Sussex being a low external fold belt to the main orogeny, which was located within the present day English Channel, [5] the remnants of the mountain belt can be seen today in Devon and Cornwall in what is known as the Cornubian Massif ...
Sutton stone has always been highly regarded: as well as being used in construction throughout the Vale of Glamorgan, it was also shipped over the Bristol Channel to North Devon and North Cornwall, which are both deficient in limestone. A major geological feature of the Upper Carboniferous rocks in south Wales is the south Wales coalfield. The ...
The geology of the national park consists of a thick succession of sedimentary rocks laid down from the late Ordovician through the Silurian and Devonian to the late Carboniferous period. The rock sequence most closely associated with the park is the Old Red Sandstone from which most of its mountains are formed.
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 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.
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 ...
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 ...
