A series of interpolated raster maps displaying concentrations of 18 chemical elements and oxides in UK stream sediments. The dataset represents the first publication of complete national maps from the Geochemical Baseline Survey of the Environment (G-BASE) and TellusNI projects. It was created by the British Geological Survey (BGS) to provide a quantitative baseline for gauging future environmental change.
Use Cases
- Modeling spatial distributions of elements like Arsenic and Lead based on the listed chemical suite.
- Establishing environmental baselines for gauging future change based on the survey's stated aim.
- Correlating geochemical signatures with underlying geology based on the dataset's national mapping scope.
- Identifying areas of potential mineral exploration or environmental concern based on element concentrations.
Strengths
- Represents the first publication of complete national geochemical maps for the UK.
- Covers a defined suite of 18 chemical elements and oxides, including Arsenic, Copper, and Uranium.
- Created by the authoritative British Geological Survey (BGS) for environmental baseline purposes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the UK-focused source.
