Coniston Limestone is the sedimentary rock formation around Coniston in the English Lake District, and forms part of the Windermere Supergroup. It is late Ordovician or possibly early Silurian in age and rests unconformably upon the Borrowdale Volcanic Group of rocks, which subsided beneath the sea, after the volcanic period.
