Description
Onshore coverage is provided for all of England, Wales, Scotland, and the Isle of Man. The data identifies linear features representing geological faults at a scale of 1:250,000, attributed by fault type (contact and non-contact). It is a generalised set of major faults, inferred from landscape evidence, created by the British Geological Survey.
Use Cases
Model regional tectonic stress fields based on fault line geometry and type.
Assess geological hazards for infrastructure projects based on fault locations.
Study rock unit boundaries based on contact faults that separate different rock types.
Strengths
Covers all of England, Wales, Scotland, and the Isle of Man.
Attributes each fault by type (contact or non-contact).
Data is provided at a consistent 1:250,000 scale.
Limitations
Row count is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
The data is generalised and shows only the location of major faults.
Provenance
Source
British Geological Survey (BGS)
Collection Method
Derived from evidence including linear depressions and displacement of topographical features.
