2001, BGS, A description of offshore gravel areas around the UK

Description

 Author: British Geological Survey. Report number: R44.This report describes the location, origin and nature of gravel patches from selected areas around the UK, mostly outside the 12 nm limit. The areas are the English Channel, the Irish Sea and the Hebrides and West Shetland shelves. Although all the gravel patches are lag deposits and exist because finer material has been winnowed away, there are significant differences in the characteristics of gravels in the 3 areas. These can be related to a combination of factors, which include the nature of the bedrock, glacial and fluvial processes and biogenic carbonate build up.
