The Coalbrookdale Coalfield is a coalfield in Shropshire in the English Midlands. It extends from Linley in the south, northwards to the Boundary Fault which runs northeastwards from the vicinity of The Wrekin. Coal-bearing strata are to be found across three synclines; the Donnington, Madeley and Coalport synclines whilst the majority of the coalfield is subject to intense faulting. The Coalfield produced coal from both deep pits and opencasts over a long period starting in Roman times. Much of the field has however been exhausted and subsequently Telford new town was built on it.〔Hamblin RJO and Coppack BC, 1995 ''Geology of Telford and the Coalbrookdale Coalfield'' Memoir of the British Geological Survey, pts of sheets 152 & 153 (E&W)〕〔British Geological Survey 2007 ''Bedrock geology: UK South'' 1:625,000 scale geological map, BGS, Keyworth, Notts〕 The following coal seams are recognised:〔Hains, B.A. & Horton, A., 1969 ''British Regional Geology: Central England'' (3rd edn), London, HMSO for British Geological Survey〕 :Middle Coal Measures : * Top : * Double : * Flint :Lower Coal Measures : * Best, Randle and Clod : * Lancashire Ladies ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coalbrookdale Coalfield」の詳細全文を読む スポンサード リンク
