  1. No agates that that I have recognised as such. Am I right in thinking that they are mostly derived from igneous rocks? Gower peninsula is made of sedimentary rocks – but there is always the possibility that rocks have ended up on this coast from other geological areas as a result of glaciation. Chert I am not certain about either, but maybe one of my geologically knowledgable readers could answer the question.
