Geological map of the British Isles
Geological map of the British Isles, with a colour-coded key (right, see C015/2656 for details and names). The geology of the British Isles is extremely varied with rocks from nearly all geological periods. The rock formation types shown are: sedimentary, metamorphic and igneous. The majority of the rocks in Ireland, England and Wales are sedimentary, with large areas of volcanic and metamorphic rocks in Scotland. The sedimentary rocks are colour-coded by geological period from most recent to most ancient (top to bottom). The oldest rocks are in north-west Scotland, the youngest in south-east England. For a simpler map with less detail, see C015/2655.

St Constantine chapel remains, St Merryn, Cornwall. 1906
A view of the ruins of the shale and slate stone medieval St Constantine chapel with two men standing to the side. The chapel is Grade II listed, and was excavated from a large grass covered sand dune which still surrounds it. It is orientated east-west and consisted of a tower at the west end, nave, chancel and south aisle. The men are possibly the photographers R. Arthur Thomas and John Charles Burrow. Photographer: Herbert Hughes.
