Treffgarne Bridge Quarry is a Site of Special Scientific Interest (or SSSI) in Pembrokeshire, South Wales. It has been designated as a Site of Special Scientific Interest since January 1954 in an attempt to protect its fragile geological elements.[1] The site has an area of 0.4 hectares (0.99 acres)and is managed by Natural Resources Wales. The name derives from the Welsh "Trefgarn".
Type
[edit]This site is designated due to its geological qualities: Cambrian sedimentary rocks exposed in a disused quarry and road cutting. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs. 30% of SSSIs in Wales are notified for geological and geomorphological features.
The sedimentary rocks have yielded a variety of fossils that indicate that the rocks were formed around 490 million years ago and therefore provide a means of correlation with other key sites such as those in North Wales and Shropshire.
