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 Black Rock Limestone is the most fossiliferous part of the lower Carboniferous succession in the Mendips. Apart from crinoids, corals and brachiopods are especially common, and different varieties of these occur at …

 · 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

 · 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 …

 · 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.
