Robeston Wathen Quarries is a Site of Special Scientific Interest (or SSSI) in Pembrokeshire, South Wales, immediately to the north of the village of Robeston Wathen. It has been designated as a Site of Special Scientific Interest since January 1967 in an attempt to protect its fragile geological elements. [1] The site has an area of 1.64 hectares and is managed by Natural Resources Wales.

Type

This site is designated due to its geological quality: Robeston Wathen Quarries SSSI has one special feature: Caradoc - Ashgill (late Ordovician) sedimentary rocks in disused quarries and a stream bed. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs.[ citation needed ] 30% of SSSIs in Wales are notified for geological and geomorphological features.[ citation needed ]

The sedimentary rocks of impure limestones, calcareous mudstones and black mudstones have yielded a variety of fossils which include evidence that the rocks are from the Caradoc – Ashgill stages - around 440 million years ago. The fossils also provide a means of correlation with other similar sites, and are catalogued by National Museum Wales. [2]

The Geological Conservation Review (GCR) is produced by the UK's Joint Nature Conservation Committee and is designed to identify those sites of national and international importance needed to show all the key scientific elements of the geological and geomorphological features of Britain. These sites display sediments, rocks, minerals, fossils, and features of the landscape that make a special contribution to an understanding and appreciation of Earth science and the geological history of Britain, which stretches back more than three billion years. The intention of the project, which was devised in 1974 by George Black and William Wimbledon working for the Governmental advisory agency, the Nature Conservancy Council (NCC), was activated in 1977. It aimed to provide the scientific rationale and information base for the conservation of geological SSSIs (Sites of Special Scientific Interest, protected under British law. The NCC and country conservation agencies were established in 1990 when JNCC became established and took over responsibility for managing the GCR site assessment process, and publishing accounts of accepted sites.

The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian to the Jurassic are represented at outcrops, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains.
