Prospective sand and gravel resources (hidden below 1:500,000)

On behalf of the Crown Estate, the British Geological Survey mapped the marine aggregate and mineral resources around Scotland. The data has been inferred from geological data, review of relevant literature and interpretation of boreholes.

The marine aggregate resources include:

1. Sand and gravel (aggregate) resources,
2. Prospective areas for Sand and gravel (aggregate) resources,
3. Fill areas where the mud content of the sand is <10% and so is not considered a Sand and gravel (aggregate) resource; but is of value because it is suitable for fill in, for example, land reclamation use.

The mineral resources include:

1. Coal resources
2. Evaporite resources
3. Metallic mineral resources

Each of the 6 resources can be viewed as an NMPI layer.
