Coastal Superficial Geology

The Geological Survey Northern Ireland (GSNI) was commissioned to complete the coastal superficial geology project in November 2022. The superficial geology dataset produced extends 200m inland from the Low Water Mark. In order to create this dataset, the GSNI used the existing 1:10,000 superficial geology map, updating and improving this existing map with the findings from the Northern Ireland 3-Dimensional Costal Survey, to provide a clear representation of the superficial geology for the entire coastline.
