The Anglian Stage is the name used in the

Marine Isotope Stage 12 (MIS 12),[2][3][4] which started about 478,000 years ago and ended about 424,000 years ago.[5][6]

Description

The Anglian stage has often been correlated to the

Mindel Stage in the Alps.[7]

The Anglian was the most extreme

glaciation during the last two million years. In Britain the ice sheet reached the Isles of Scilly and the Western Approaches, the furthest south the ice reached in any Pleistocene ice age.[8] In the south-east of England it diverted the River Thames from its old course through the Vale of St Albans south to its present position.[9]

This stage had been equated to the Kansan Stage in North America. The stage names "Kansan", "Yarmouth", "Nebraskan" and "Aftonian" were later abandoned by North American Quaternary geologists and merged into the Pre-Illinoian stage.[10][11] The Anglian Stage is now correlated with the period of time which includes the Pre-Illinoian B glaciation of North America.[4][11]
