Lily-Lagoon 3D geological and geophysical model

The Lily-Lagoon 3D geological model was constructed in GeoModeller^TM and built entirely by implicit means, whereby surfaces bounding unit volumes were interpolated from geological observations (stratigraphic and fault contacts, dips, and strikes) via prior geological knowledge encoded in a matrix of rules defining the relative timing of all model components. As a useful model can thus be constructed with far fewer user-entered points than explicit modelling, this makes it much easier to modify the model in response to indications from subsequent geophysical modelling or emergent 3D geometric plausibility.

These 3D models are being distributed primarily as a Geoscience ANALYST project. Geoscience ANALYST is visualisation and communication software for GoCAD^® 3D models, made freely available by Mira Geoscience.
