Implicit geological modelling : a new approach to 3D volumetric national-scale geological models

This report provides information on implicit geological modelling and a possible application in the construction of national-scale (in the UK context) volumetric geological models. The stratigraphy of the UK is reviewed in the context of unconformity-bound stratigraphic sequences and how these can be applied in the modelling process. A range of input datasets are outlined with discussion on how these can be used and where gaps exist in available information. Model outputs are discussed highlighting the new opportunities offered by 3D stratigraphic grids. Some of the advantages and disadvantages of implicit modelling are discussed.
