BGS Geological Factor Maps added to MAREMAP

A series of maps describing geological factors relevant to offshore seabed activities. Produced in collaboration with The Crown Estate in 2014. The new layers are:

  • BGS Quaternary Deposits Thickness
  • BGS Quaternary Deposits Summary Lithologies
  • BGS Bedrock Summary Lithologies

BGS Quaternary Deposits Thickness

The Quaternary Deposits Thickness dataset is a digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which shows the thickness of the deposits over bedrock in three categories: <5m, 5-50m, and >50m Quaternary cover. These depth bands were picked because they represent the horizons that have impact on offshore infrastructure deployment. The map is derived from (unpublished) BGS 1:1,000,000 scale Quaternary digital geological mapping.

The map was produced in 2014 in collaboration with The Crown Estate as part of a project to assess seabed development opportunities across the UKCS.

This map has been released for viewing on the Offshore GeoIndex alongside a series of other offshore geological maps from the BGS

BGS Quaternary Deposits Summary Lithologies

The Quaternary Deposits Summary Lithologies dataset is an offshore digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200 m, which groups the deposits into classes based on similar engineering geology characteristics. The map is derived from (unpublished) BGS 1:1,000,000 scale Quaternary digital geological mapping.

The map was produced in 2014 in collaboration with The Crown Estate as part of a project to assess seabed development opportunities across the UKCS.

This map has been released for viewing on the Offshore GeoIndex alongside a series of other offshore geological maps from the BGS.

BGS Bedrock Summary Lithologies

The Bedrock Summary Lithologies dataset is digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which groups the bedrock lithologies (rock types) into classes based on similar engineering geology characteristics. The map is derived from the 1:250,000 scale digital bedrock map of the UKCS, called DiGRock250k, which is available separately from the BGS.

The map was produced in 2014 in collaboration with The Crown Estate as part of a project to assess seabed development opportunities across the UKCS.
