Beestonian stage
Encyclopedia
The Beestonian Stage is the name for an early Pleistocene
stage used in the British Isles
. It precedes the Cromerian Stage and follows the Pastonian Stage. This stage consists of alternating glacial and interglacial phases instead of being a continuous glacial epoch. It is equivalent to the European Bavellan, Waalian, and Eburonian stages combined and Marine Isotope stages 22 to (60?). The Beestonian Stage and Marine Isotope Stage 22 ended about 866,000 years ago.
This stage had been equated to the Nebraskan Stage in North America
. However, the Nebraskan Stage, along with the Kansan and Aftonian Stages, have been abandoned by North American Quaternary geologists and merged into the Pre-Illinoian Stage. At this time, the Beestonian stage is correlated with the period of time, which includes the Pre-Illinoian F, Pre-Illinoian G, and Pre-Illinoian H glaciations of North America.
It is named after Beeston Cliffs near West Runton
in Norfolk
where deposits from this stage are preserved.
Pleistocene
The Pleistocene is the epoch from 2,588,000 to 11,700 years BP that spans the world's recent period of repeated glaciations. The name pleistocene is derived from the Greek and ....
