Moray Firth 3D onshore-offshore modelling Clive Auton, Sarah Arkley and Alick Leslie British Geological Survey, Murchison House, Edinburgh EH9 3LA Calculated onshore-offshore model of regional fault network and Phanerozoic cover rocks of the Inner Moray Firth Caption text here. The model merges data generated for UKGB3D cross- sections, calculated faults from the Great Glen structural model (Top Left), with data derived from regional onshore and offshore maps, and from recent onshore bedrock surveying (Bottom Right), in a region-wide synthesis.
