Lower Carboniferous Shallow-Marine Limestone of the Great Orme, North Wales, UK

Course Description:

Spectacular cyclothems of Asbian to Brigantian limestones are exposed on the Great Orme peninsula in Llandudno, North Wales. These rocks were deposited on a shallow carbonate shelf during the later stages of the Lower Carboniferous transgression, and display the well-bedded cyclicity characteristic of shallow-water carbonate factories. The shallowing up succession is capped by karst and the deposition of calcareous sandstone in a shoreface setting. Dolomitised and mineralised fractures are in evidence, as are a range of fossil biotas. This trip can also be combined with one or both of our Anglesey field trips for a fuller picture of Carboniferous geology.

This field trip can also be delivered in conjunction with our Carbonate Reservoir Geology course or our Exploration Workshop.
