This is a 5-night trip with 4 days in the field.

Anglesey is regarded as a “classic” area of British geology; while its oldest rocks appear to be unrelated to those of the rest of the British Isles, the remainder provide a detailed record of events which led to the formation of southern Britain. Formed between 650 and 300 Ma, they include high grade gneisses, a granite pluton, metasediments, sandstones, mudstones and the famous Anglesey Blueschists. There are also Paleogene dykes and abundant glacial features. A number of NE–SW faults slice the island into blocks; large sandstones blocks are thought by some geologists to mark the location of an ancient subduction zone. The original map was published in 1920 and BGS is currently undertaking a project of new research into the island’s geology.
