dead end dating book 6 by kimberly raye - Validating a process model

To create meaningful and robust models, proper forethought, planning and understanding of the area’s geology is required.Implicit modelling allows you to build the model you have in mind and apply various changes to test possibilities suggested by analysis of the data.

The implicit modelling algorithm may be indicating a dip on an intrusion normally thought to be vertical.

We may write off the result because we “know” the intrusion is vertical.

Both wireframed and implicit geological models require understanding of the geology and the processes around creating them.

For implicit modelling, you need a basic understanding of the interpolation process.

Now that it has been picked up by the masses and a large number of software companies are building modules, I fear we are starting to move into misuse.

Sometimes implicit modelling may not be the best tool for the job.

A significant step in the basement co-incident with the grade shows the location of what was later modelled as a cross-cutting fault and which subsequently became the feeder for the mineralisation, completely turning the exploration model on its head.

(Legend; Ultramafic = purple, volcanic = green, sediments = blue and cover = brown).

Equally important is being able to tell which aspects of geology are most important for each deposit modelled and how they affect the result.

Sometimes what we know about a deposit is simply wrong (Figure 3).

Combining the sampling, mapping and past thought, even from the last year, with the current understanding always results in a more robust model.
