2021-4-29 Carboniferous Limestone is a type of limestone rock, which was laid down in Great Britain and Ireland in the Dinantian stage of the Carboniferous period. It was formed between 363 and 325 million years ago. It is one of the three most common types of limestone found in Britain, along with chalk and Jurassic limestone.

The Carboniferous Limestone along tile outcrop described presents many features of special interest. In the eastern portion the o~-erstep of tile Millstone Grit persists northwards and proceeds much further, until in the extreme north-east, near Abergavenny and Criekh~weit, there remain rather less than Ioo feet of Avonian strata, belonging to the ('!cis/@ora Zone.

The lowermost and hence oldest rocks from the Carboniferous period are the Carboniferous Limestones which form a 1-3km wide belt of country running from west to east across the southern slopes of the Black Mountain / Y Mynydd Du and Fforest Fawr. To the east, and offset southwards by the Cribarth Disturbance, is a further narrow belt of limestone ...

2020-1-17 Some 50 km2 of the Carboniferous Limestone outcrop in the southern half of the Peak District shows evidence of alteration of the original limestone to dolomite, locally known as dunstone from its dull brownish grey colour on weathered surfaces. The dolomitized area (Fig. 1) is less than a tenth of the total White Peak limestone outcrop, but

2018-1-12 Merryfield Mines in Ashfold Gill. It has been suggested that the presence of strong permanent springs, where the lowest beds are exposed in Trollers Gill, indicates that here the beds (S) rest on a pre-carboniferous ridge. 1 The limestones of D1 age carried the most important ore shoots, mainly where they were underneath a cap of Millstone Grit Shales.

MANY of your readers are aware that the fact of the occurrence of gold in Lower Carboniferous conglomerate as in New South Wales is not at all new. The Gay's River Gold Field of Nova Scotia, where the gold occurs in Lower Carboniferous conglomerate resting on the edges of Cambrian slates having small veins of auriferous quartz, was first pointed out by Prof. Hartt and elaborated by myself in a ...

2021-1-28 Investigations were undertaken at the Xutuan and Renlou coal mines in Huaibei coalfield, Anhui Province, China to determine the effects of mining on the geochemical evolution of groundwater in the area. A total of 77 samples were collected between 1999 and 2017 from Neogene, Permian, and Carboniferous aquifers in two coal mines for hydrogeochemical analysis.

2011-6-2 This 1989 book covers the geology and geomorphology of the Carboniferous Limestone areas of Wales, and summarises the state of knowledge of the main cave systems including the longest and deepest in Britain. It sets out to assess the morphological evolution of the cave systems and the associated landscape features, particularly in light of the effects of successive glaciations.

Lead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb 5 (PO 4) 3 Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver.
