Cosmogenic 10 Be exposure age dating across Early to Late Weichselian ice‐marginal zones in northwestern Russia
Rock samples from the Kanin Peninsula and the Timan Ridge were analysed for in situ cosmogenic 10 Be for exposure age dating purposes. Crystalline rocks were sampled at four sites on the Kanin Peninsula, either from bedrock outcrops or from glacial erratics, giving overall similar 10 Be ages. Outcro...
