Structural Ribbons and the Intrusion Modeller

MMOB 2026 introduced the Structural Ribbon layer, a polyline with dip and dip direction at each node, visually indicated by coloured bands and interactive discs. It integrates with the Implicit Modeller for intrusions using the RBF algorithm, guiding the model to respect known dip directions. This feature enhances implicit modelling by allowing flexible control over dips, improving accuracy and ease in setting up geological intervals.

MMOB 2026 introduced the Structural Ribbon layer:

This is essentially a polyline that has dip and dip direction configured at each node. The blue and pink bands indicate the up/down dip directions. The discs are can interactively rotate in the viewer.

Once configured, Structural Ribbons can be incorporated into the Implicit Modeller for intrusions to use with the RBF algorithm:

Here's that Structural Ribbon in relation to Oxide drilling data, and we're attempting to model the lower intervals in blue. Along the western edge, we have some data that tells us the fresh material should dip downwards beyond our drillholes. Our Structural Ribbon will influence the implicit modeller to respect that knowledge:

When we run the Fresh intervals in the Intrusion Modeller, the difference is clear. The left side of the image below is the result without the Structural Ribbon. The right side is the result with the Structural Ribbon. 

Structural ribbons have the potential to add more flexible control over your implicit modelling. It's a quick and easy way to setup approximate (or exact if you have that data) dips across an area.
