About this Event
The Great Limestone is the most extensive limestone in northern England stretching from north Northumnerland to Cumbria and Yorkshire. It marks the boundary between the Visean and Namurian of the Carboniferous where basin evolution changed from rifting to thermal subsidence. It has been quarried in Weardale on a large scale with excellent exposures in Ashes Quarry and along the nearby Bollihope Burn. The limestone also hosts much of the mineralisation associated with the North Pennines and we shall look for some evidence of features related to the mineralisation. Fossils are also present.
