网页Surface Features. The 'classic limestone walk' is a circular 10 km route from the field centre on the north side of Malham Tarn to the village of Malham, UK via Watlowes Valley and back again via Gordale Scar. Small surface depressions called shakeholes, which are 1-3m deep and 3-5m across, form as a result of the subsurface collapse of limestone.网页Robust paleomagnetic results through geological time are one of the keys to understand the drift history of the eastern Qiangtang terrane (EQT). Here, we presented comprehensive petrographic observations and rock magnetic and paleomagnetic analyses of the early Carboniferous Upper Zaduo (ZD) limestone Formation (C1z2) from the …اقرأ أكثر
网页Deposits of crinoidal limestone approaching 150 metres (500 feet) are not uncommon in intervals of Mississippian age, particularly in North America, and they are exploited as quarry stone. In addition to the crinoidal limestones, oolitic limestones and lime mudstones also formed in shallow-water marine environments of the Mississippian.网页The Carboniferous Limestone - British Geological Survey ... The Carboniferous Limestone as an aquifer.
