Description
Area,7.03 hectares 17.37 ac Description Trowbarrow Quarry, which is disused, lies 1g kilometres east of Silverdale and affords a most interesting section through the Lower Carboniferous Urswick Limestone Asbian Stage. It shows a variety of carbonate lithologies of outstanding interest for the light they throw on aspects of carbonate sedimentology and diagenesis. The site lies on the southern margins of the Dinantian Northern England Platform and a variety of sedimentary types and features occur, including palaeokarstic surfaces, clay wayboards, coals, stromatolites, oncolites, pseudobreccias, as well as more normal marine carbonates with shelly faunas. This is an outstanding locality for the study of later Dinantian Asbian– Brigantian faunas and sedimentary environments.
