| Zusammenfassung |
| Informed decision making and assessment of uncertainty and risk in a geological context requires a sound grasp of key stratigraphical and structural surfaces in 3D. This British Geological Survey (BGS)/Geological Survey of Northern Ireland (GSNI)/Geological Survey of Ireland (GSI) collaboration is constructing a regional-scale model of the fundamental architecture of the British and Irish upper crust at a nominal scale of 1:500 000 – offshore and onshore. The aim is to provide a model that can be used as a dynamic context for the widest possible range of larger-scale models relevant to geological survey, investigation, research and education. The model will also be a framework within which the geological community can communicate effectively with a broad spectrum of planners, designers, and construction engineers – realising our geological framework for society’s benefit.
We are constructing this model, within the BGS GSI3D package but is interoperable with other modelling packages such as GOCAD® and GeoVisionary. The model is constructed around a framework of 15 km deep geological cross-sections that capture published geological mapping and 3D interpretation, integrated with the interpreted results of regional geophysical potential field and seismic survey. We aim ultimately to have a volume-attributed model which can host site/topic specific models at a variety of scales. Our ‘Test Block’ started with Northern Ireland (GSNI Tellus2 funded) and the northern half of the Republic of Ireland (GSI); continued development has seen the model expand across all of Scotland, and Northern England. The remainder of Britain (BGS GB-3D project) and Ireland will be incorporated in due course, and as the development continues we will seek input from academia and industry via a user portal. This short demonstration is intended to provide insight into the progress to date, and to encourage interested groups to contribute to the developing model. |
