Bedrock Geology 1:100,000 Series

Data represents a seamless bedrock geological dataset encompassing Republic of Ireland and parts of Northern Ireland. The seamless geological dataset was created from the GSI Bedrock 1:100,000 scale digital geological map series. The dataset comprises 6 key shape files. 1 Bed100k.shp - A polygon shapefile that contains bedrock geological information on Stratigraphy, Igneous, Lithology and Diagenetic codes, their unit names and brief descriptions. 2 Index100k.shp- An overlay polygon index of 1:100,000 scale printed map sheets. 3 Struc100k.shp,Structural Linework - A linework shapefile that contains structural geological linework codes and descriptions. 4 Strat100k.shp Stratigraphic Linework - A linework shapefile that contains stratigraphic geological line codes and descriptions. 5 Sect100k.shp Cross section - A linework shapefile indicating the locations of map sheet cross sections as per paper printed maps.
6 Mins100k.shp - A point shapefile contains mineral and quarry descriptions from Bedrock 1:100,000 map series. This is a subset of the MINLOCS database held by Minerals Section in the GSI.
The original printed map series and seamless dataset is based on the Ordnance Survey of Ireland topological maps at 1/2 inch to one mile which were converted photographically to the metric 1:100,000 scale by the Geological Survey of Ireland Cartographic Unit. The topological base maps are not provided in the data set.
