A provisional Quaternary and Neogene lithostratigraphical framework for Great Britain
Abstract This paper presents an overview of a provisional lithostratigraphical framework for the Quaternary and Neogene deposits of Great Britain (England, Scotland and Wales) (onshore). The objective is to provide a workable framework to aid future Quaternary mapping and research, and a stratigraph...
