Stream sediment geochemical atlas of the UK

BGS Research — Applied geochemistry

The aim of the national geochemical survey (G-BASE in Great Britain and TellusNI in Northern Ireland) was to improve understanding of our geology, mineral resources and environment, in order to provide quantitative evidence against which to gauge future environmental change. It is a milestone publication, representing 45 years of work, that characterises the chemical quality of the UK surface environment.

The Stream sediment geochemical atlas of the UK is an interactive pdf document designed to be downloaded in two-page view using Adobe pdf software (e.g. Adobe Reader, Adobe Acrobat). If viewed using other software, e.g. within your browser, certain interactive elements may not display or function as intended.

The concentrations of 18 chemical elements analysed from approximately 111 000 rural stream-sediment samples collected at a sample density of about one per 2.5 km2 are presented.
