I agree entirely with Bill Morris' comments on the way that interpretation has changed with the advent of imaging. I also agree with his comments on what will eventuate with 3D visualization. What I do not understand is Geosoft's reluctance to tackle this new exciting world. Through a combination of a Windows version of Magmod and a 3D version of WholePlot one would have a very powerful interpretation tool. It would be great to view in a 3D sense where our modelling sits in relation to previous drilling. Did the drilling hit the body or with improved modelling and visualization can we prove that it did not? The notion of doing all the modelling in another package i.e other than Montaj as proposed by Geosoft is fine in principle but bearing in mind that exploration budgets are diminishing not growing and software budgets are not above all this when it comes to annual maintenence bills some hard decisions generally have to be made.

May I make a suggestion: Prior to our current fascination with image production we spent a lot more time computing the geometry and physical property of magnetic models. The outcome of this modelling exercise was a pseudo-geological map that showed the distribution of tabular bodies, pipes, steps etc. From this information the geologist in us took this information to develop a model of what was happening. Now we are on the threshold of 3D modelling. Surely we can now take our simple models place them on a Maplot image and look at this in 3D to develop better geological models. Perhaps this where teh Quikmag program of Encom is heading Bill Morris
