Britain and Ireland have a remarkably varied geology for so small a fragment of continental crust, with a fine rock record back through three billion years of geological time. This history would have been interesting enough if it had been played out on relatively stable continental crust. However, Britain and Ireland have developed at a tectonic crossroads, on crust once traversed by subduction zones and volcanic arcs, continental rifts and mountain belts. The resulting complexity is instructive, fascinating and perplexing.
