Timing of the maximum extent of Late Pleistocene glaciation in NW Europe: Evidence from Lundy

This paper presents geomorphological and cosmogenic isotope evidence for the glaciation of Lundy. 26Al/10Be analyses from glaciated bedrock surfaces reveal an exposure age of c. 35-40ka. This challenges the long-established view that the last glaciation this far south must belong to Middle Pleistoce...

Description
Summary:This paper presents geomorphological and cosmogenic isotope evidence for the glaciation of Lundy. 26Al/10Be analyses from glaciated bedrock surfaces reveal an exposure age of c. 35-40ka. This challenges the long-established view that the last glaciation this far south must belong to Middle Pleistocene, such as the Anglian Stage (c. 480-420 ka), when ice reached as far south as London. Instead, the findings suggest glaciation of Lundy during the last ice age (Devensian Stage). However, the ages from Lundy suggest that the ice sheet in this area was at its largest extent well before the global Last Glacial Maximum at c. 26-21 ka
