Traces of volcanic ash from the Mediterranean, Iceland and North America in a Holocene record from south Wales, UK
A tephra record is presented for a sediment core from Llyn Llech Owain, south Wales, spanning the early‐ to mid‐Holocene. Seven cryptotephra deposits are discovered with three thought to correlate with known eruptions and the remaining four considered to represent previously undocumented events. One...
