Variably-cemented conglomerate – a virtual sample

Posted by Callan Bentley

Here’s another example of a visualization combination that leverages the advantages of the GIGAmacro system with the 3D ‘virtual sample’ perspective of the Sketchfab-hosted model: the same sample presented in both formats.

In this case, it’s a lovely example of a conglomerate that I found in our lab at NOVA, showing variations in the level of cementation around a central ‘nucleus’.

It’s interesting to me that the center of the specimen is less well-cemented than the intermediate depth. I guess there must have been some sort of piping process to produce that “doughnut” shaped pattern in cross-section, or else a two-stage process of cementation and then de-cementation over a lesser area.

At any rate, have fun examining it!
