— Al Khlata Formation is an oil-bearing reservoir in Oman. Its origin during the Late Palaeozoic Gondwana glaciation in the southern part of the Arabian Peninsula is demonstrated by the glaciogenic deposits of the formation in Oman. Outcrops of the Al Khlata Formation occur in a belt parallel to the Huqf fold axis, the best outcrops being …

Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain, Ireland, France and Belgium that were deposited during the Dinantian Epoch of the Carboniferous Period.These rocks formed between 363 and 325 million years ago. Within England and Wales, the entire limestone succession, which …

— In the UK, the Carboniferous Limestone is proven as a productive aquifer, hosting the circulation of deep hydrothermal fluids responsible for the thermal springs in Bath (Figure 3), Bristol, the Taff Valley and Buxton. The advantage of the Carboniferous Limestone as a resource is that it covers large areas of the UK subsurface and coincides ...

The Carboniferous Limestone has been folded and faulted by massive Earth movements which can be seen by the fact that the rocks are now above sea-level and no longer horizontal. The rocks generally dip (slope) gently eastwards and, in some places, clear folds in the rock can be seen especially at the Great Orme and Bryn Alyn (Denbighshire). ...

Dolomite is the dominant carbonate rock in Precambrian and Paleozoic sequences, whereas limestone is dominant in carbonate units of Mesozoic and Cenozoic age (Ronov, 1983). On the basis of their abundance alone, about the same as that of sandstones, carbonate rocks are obviously an important group of rocks. They are important for other …
