Solva Group
The Solva Group is a Cambrian lithostratigraphic group (a sequence of rock strata) in west Wales. The name is derived from Solva on the west coast of Pembrokeshire where the strata are well exposed in coastal cliffs. This rock succession was formerly known as the ''Solva Series'' and ascribed to the British regional stratigraphic unit ‘’St David’s Epoch’’, though these terms are now obsolete. ==Outcrops== These rocks are exposed, along the north coast of St Brides Bay south of St Davids and in particular at Caer Bwdy Bay just southeast of the city where they are seen to overlie the Caerbwdy Sandstone Formation. They are exposed again in the sides of the ria at Solva and occur more widely inland of the village though exposures are less frequent. There are less extensive outcrops further west at St Justinian and on Ramsey Island. To the east they occur again north of Newgale and at Tancredston and to the west of Wolf's Castle.〔British Geological Survey 1:50,000 scale geological map (England & Wales) sheets 209 ''St David's'', 210 ''Fishguard''〕
