It might be if someone sheared off part of Canada and shifted it back to Blighty. Or are you suggesting this area previously joined prior to the Atlantic spreading? The geology of the English Liverpool can be found here - mainly sedimentary.

No problem. British metamorphic gems might include the Iona and Cuillin (Skye) Marbles From Ireland there is the Connemara Marble It turns out that in Scotland: Ruby Bay (Elie) Pyrope Garnet are volcanic in origin Scottish Brucite and Forsterite Durness MarbleSome of these Prehnite may well be metamorphic, given their location in e.g. Lewisian terrane in the west HTH
