Cloford Quarry () is a geological Site of Special Scientific Interest to the south of the A361 approximately north of the hamlet of Cloford and west of Nunney on the Mendip Hills in Somerset. It was notified in 1994. It is a Geological Conservation Review site important for the exposures of sediments of Triassic and Jurassic age which occur in major fissures within the Carboniferous Limestone laid down beneath the sea some 350 million years ago. Fissures, created by the uplift, folding and faulting of the Carboniferous Limestone, periodically opened and closed which were filled with deposits of Rhaetic, Hettangian, Sinemurian, Pliensbachian, Toarcian and Bathonian ages. The surface also contains large number of borings made into it by bivalved molluscs living in the Jurassic seas. No other site in Britain shows such a variety and abundance of sediment-infilled fissures of this age.〔 (English Nature citation sheet for the site ) (accessed 7 August 2006)〕 In 2006 planning permission was granted for continued extraction of limestone until 2042. Cloford Quarry was the main location used for the planet Lakertya in the ''Doctor Who'' story ''Time and the Rani''.〔(【引用サイトリンク】title=Cloford Quarry )〕 Shots filmed here include the exterior of the Rani’s laboratory. == See also == * Quarries of the Mendip Hills 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「Cloford Quarry」の詳細全文を読む スポンサード リンク
