Creating realistic 3D Geology models rapidly, using geophysicsto test them

The traditional method of recording and communicating an understanding of the geological structure of a region has<br>been to create a map of the geology. Today there is a growing trend to use three-dimensional models of geology. One<br>of the challenges with 3D geology modelling is that it is frequently difficult to incorporate new data, and revise the<br>model. The potential field geology modelling method described here automates the task of model building, and<br>computes a model directly from the data (the geology observations). The method has been implemented in the 3D<br>GeoModeller software.
