1971 to 1986 mineral resource maps produced by the British Geological Survey's Industrial Minerals Assessment Unit for Great Britain. The collection includes sand and gravel resource maps, with some covering conglomerate, limestone, dolomite, and celestite in specific regions. Maps show locations of resource blocks, deposit categories, and boreholes with indicative logs.
Use Cases
- Identify locations of IMAU mineral resource blocks for strategic land-use planning and resource development.
- Analyze categories of resource deposits to assess regional availability of materials like sand, gravel, and limestone.
- Map borehole locations with indicative logs for environmental assessment and hazard indication in mined areas.
Strengths
- Covers a 15-year production period from 1971 to 1986.
- Includes maps at detailed scales of 1:25,000 and 1:50,000.
- Majority of maps cover 10 km x 10 km grid squares, providing localized detail.
Limitations
- Data originates from scanned printed maps, which may introduce resolution or legibility issues.
- Focus is primarily on Great Britain, limiting geographic applicability.
- Temporal coverage ends in 1986, so resource assessments may not reflect current conditions.
