Description
22 regional geochemical atlases for Great Britain, published by the British Geological Survey between 1978 and 2000. The collection provides interpolated heat-maps for each analyte from the G-BASE project, covering stream sediment, soil, and stream water samples.
Use Cases
Analyze spatial patterns of analyte concentrations across regional heat-maps to identify geochemical anomalies
Compare stream sediment, soil, and stream water geochemical baselines for environmental change studies
Use the systematic baseline data as a historical marker to measure future environmental change in Great Britain
Strengths
Covers 22 distinct geographic regions across Great Britain
Provides data across three sample media: stream sediment, soil, and stream water
Represents a systematic national baseline survey conducted over a 22-year period
Limitations
Data is presented as static, hard-copy atlas heat-maps, not raw point measurements
Temporal coverage ends in 2000, lacking recent environmental changes
Digital versions are only available for specific sub-regions, not the full collection
Provenance
Source
British Geological Survey (BGS)
Collection Method
G-BASE (Geochemical Baseline Survey of the Environment) project field sampling and analysis
Time Range
1978 to 2000
Freshness
null
Geography
Great Britain, covering 22 regions including Shetland, Orkney, Wales, Lake District, and others
Primary data format is HTML documentation for hard-copy atlases; raw analytical data or GIS-ready layers may require separate acquisition from BGS digital products.
