Quaternary deposits summary lithologies across the UK Continental Shelf (2014 Version)

The Quaternary deposits summary lithologies dataset is a 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 The map is derived from (unpublished) BGS 1:1,000,000 scale Quaternary digital geological mapping, so is effective at that scale. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The divisions on the map combine the Quaternary deposits into 7 categories of similar strength and lithological variability, each with a ‘Category’ title that summarises their main lithological character: diamict; firm to hard interbedded (layered); firm to hard mud; sand and gravel; soft interbedded; soft mud; undifferentiated. These categories can be used as a basis for assessing, in conjunction with a range of other geological factors, the geological constraints on engineering structures at or close to the seabed. The data are held by the BGS as an ESRI ArcGIS Shapefile.

Lithostratigraphic units defined in the BGS 1:1000000 Quaternary Geology map were assessed in terms of strength and lithological variability. Lithostratigraphic units were then grouped into classess depending on their expected impact on engineering activities. The resulting classes were attributed in GIS to shapefiles defined by BGS Lex Codes (Lithostratigraphic units). Part of this dataset, mainly around the coastline, has been coarsely interpolated so that its extent covers the whole factor map area. The methodology used to fill in no-data areas consists of dividing these areas into square grids (10x10km) where each polygon within the grid will get assigned the category value of the polygon sharing its border in an iterative process until all polygons within the grid have a category value. This iteration was done by running the ArcGIS Spatial Join tool several times with the match option “SHARE_A_LINE_SEGMENT_WITH”. The final step is merging the now attributed grid to the dataset and dissolving the polygons.
