Bluestones all over the place.....


Bluestone at Porthleven -- the Giant's Quoit

If we use the term "bluestone" as meaning anything that isn't sarsen (which is the only meaning we can give to the term) then of course we find bluestones all over the place. There are bluestones at Court Hill, in the glacial deposits; at Fremington, in glacial deposits; on the Scilly Isles; in fissures in the limestone on the Mendips; in the Bath area; at Stanton Drew; and as isolated boulders here, there and everywhere. Some of these have been incorporated into megalithic structures. Much more info is in the book! And I'm sure more info will emerge.

The Court Hill erratics could have come from the Gower (Carboniferous Limestone) or from the Vale of Glamorgan (Lias and Trias) or from the ORS which is very extensive in the Brecon Beacons and SE Wales. I'm not sure that anybody has done sufficiently detailed work on the erratics in the glacial deposits of SW England to decide on how far-travelled they are -- it's difficult with sedimentary rocks. (Just look at the long debate about the origin of the Altar Stone!)
