The most widely-distributed sedimentary rock is Carboniferous limestones, the main rock across much of the central lowlands. In most places the limestones are overlain by materials deposited during or after the last glaciation. In a few areas, however, the cover is thin or non-existent and a distinctive limestone landscape has developed.

The Carboniferous Limestone as an aquifer. The Carboniferous Limestone is a massive, well-fissured karstic limestone that gives large water supplies of up to 175 l/sec from resurgences in the Mendips and South Wales, and borehole yields of up to 40 l/sec from the upper parts of the aquifer.

Although a very large amount of information concerning the lithology of the Carboniferous Limestone is now available, that of no section has hitherto been described in detail, and it seemed that a full account of the rocks of the classical Avon Section might prove of value. The first full account of the composition or structure of one of the rocks of that section was W. W. Stoddart's ...

Review some answers and establish that students know that limestone is formed mainly of calcium carbonate, which comes from the remains of coral and sea shells and was formed on the seabed. We'll look at one particular type of limestone called carboniferous limestone. This creates distinctive landscapes because it is susceptible to chemical ...

The Carboniferous Limestone rock of the White Peak of Derbyshire is about 350 million years old and made from the limey shells, bones and secretions of marine life. Creatures living in ancient seas obtained calcium from sea water to make their shells, bones, and structures. When these creatures died they sank to the sea floor where they were ...

Carboniferous Period, fifth interval of the Paleozoic Era, succeeding the Devonian Period and preceding the Permian Period. In terms of absolute time, the Carboniferous Period began approximately 358.9 million years ago and ended 298.9 million years ago. Its …

The direct use of geothermal heat from the Carboniferous Limestone Supergroup ('Carboniferous Limestone') could make a significant contribution to delivering affordable, low-carbon heating to thousands of buildings, homes and offices through a district-heating system, as well as providing heating for agriculture and horticulture.

The Carboniferous Limestone consists of eight lithologies: shelly, crinoidal, oolitic, micritic, dolomite and impure limestones, siliceous sandstone and mudstone. Samples of these rock types, apart from the mudstone, have been collected, sectioned, described in detail, the nine major elements determined, and the insoluble residue analysed by X ...

Black Rock Limestone Subgroup. The Black Rock Limestone is the most fossiliferous part of the Carboniferous Limestone in the Mendips. The remains of crinoids, brachiopods and corals are especially abundant, and three broad faunal subdivisions can be recognised.

The Carboniferous Limestone successions in Cotunty Clare and County Limerick are closely similar, hence this pioneer work of Douglas' has been constantly referred to. Ashby (1939) and Delepine 1949) have described areas in eastern County Limerick, in which volcanic roeks form an important part of the Carboniferous Limestone succession.

Carboniferous limestone is an example of a pervious rock, as it allows water to flow through the joints and bedding planes. The main processes, which affect it, are carbonation and solution. The two best areas of carboniferous limestone in Britain are the Yorkshire Dales and the Peak District.

The geological formation of carboniferous limestone rock is illustrated. Fossil formation is mentioned but not shown. An animation shows the build up …

Carboniferous rocks in Europe and eastern North America largely consist of a repeated sequence of limestone, sandstone, shale and coal beds. In North America, the early Carboniferous is largely marine limestone, which accounts for the division of the Carboniferous into …

This Lower Carboniferous limestone comes from the Whitesands and Barns Ness area, South-East of Dunbar, North Berwickshire, Scotland. The rock contains distinctive Koninckophyllum corals and brachiopod shell fragments cemented by a calcium carbonate rich mud known as micrite.

Limestone samples were collected from the early Carboniferous Huangjin Formation in the Mopanshan section, which is located ~15 km southeast of Guilin city, Guangxi Province. The Mopanshan section was located in a carbonate platform during the Carboniferous (Fig. 1 ).

A limestone pavement is an area of almost bare, flat rock and is arguably the most fascinating feature of any area of carboniferous limestone. They develop after the rock has been exposed by the scouring action of an ice sheet or glacier. Existing joints are subsequently exploited by the action of chemical weathering carbonation to form deep ...

The lower group coal is mined in this area, and the hydrogeological type of the area is very complex. According to the relevant data, No. 10 stratum Carboniferous limestone is the immediate roof of No. 16 coal seam in the mining area. No. 13 stratum Carboniferous limestone and Ordovician limestone are the direct and indirect water-filled aquifers of No. 16 coal seam and No. 17 coal seam ...

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 running from Pontneddfechan through …

What you have is a piece of cherty limestone that contains individual crinoids stem fragments (the round objects that look like compressed coral), bryozoans (the small fans are fronds of a fenestrate bryozoans and some of the branch-like objects are also bryozoans), and it looks like the mold of small clams (bivalves).

Carboniferous limestone 1. Formed during carboniferous period 340 mil years ago Formed by accumulation of CaCO3 in warm tropical areas Corals and shelfish found as fossils in this rock Forms bands – e.g. Pennine Hills in UK, Mendips 2.

Carboniferous limestone is greyish and hard and made from the remains of corals. Jurassic limestone is yellowish and softer. It is oolitic (made from little eggs of calcite). Cretaceous limestone ...

CARBONIFEROUS LIMESTONE OF DERBYSHIRE. 1. PARENT MATERIALS BY C. D. PIGOTT The Botany School, Cambridge INTRODUCTION The main outcrop of Carboniferous limestone in the south Pennines is about 175 square miles (480 sq. km) in extent with several small inliers in younger rocks beyond the southern boundary.

The rocks of this region have been thrown into a series of more or less parallel folds with a general trend from east-north-east to west-south-west. The most important upfold is the Clitheroe Anticline, dissected by the Ribble, which runs west-south-westwards in the neighbourhood of Clitheroe, exposing the Carboniferous Limestone along the axis.

This Lower Carboniferous limestone contains many fragments of crinoid ossicles that were once the stems of ancient marine animals attached to the sea bed, sometimes called sea lilies. There are also many fragments of brachiopod shells. The sample comes from Bucket Rocks, Berwick upon Tweed, England, and is cemented by a carbonate rich mud.
