Smarts Quarry is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, designated in 1987 for its geological features. [1] [2]
Smarts Quarry SSSI is located approximately 0.5 miles (0.80 km) east-north-east of Mynydd-y-Garreg, and covers 2.6 hectares (6.4 acres). [1] [2]
The SSSI citation for Smart Quarry specifies the importance of "abundant, bivalve produced, stellate feeding traces on a bedding surface" within the Namurian quartzite of the quarry. The citation finds such traces unique within the Namurian basal grits of South Wales and suggestive of an estuarine rather than a shoreline sedimentary deposition of the quarry stone. [2]
A site of special scientific interest (SSSI) in Great Britain, or an area of special scientific interest (ASSI) in the Isle of Man and Northern Ireland, is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".
