Creating a Vulcan Surface Triangulation

Triangulated surfaces are often the foundation of modeling a mineral deposit.  Whether the surface is current topography, a fault plane or a thickness isopach an accurate surface is an integral part of the model.  Creating this surface should be simple and easy, but in Vulcan there are so many options.  Where do you start?  This tutorial shows you how to create a simple surface triangulation in Vulcan and touches on some of the options you may want to use during creation.

Creating a surface triangulation begins with the input data.  This data can be a topography map with strings at actual elevation or a set of points like drillhole collars or grade values.  The data should be loaded in Vulcan and displayed in Envisage.  Create the triangulation using the menu Model > Triangle Surface > Create.  The panel that pops up will have several tabs, each with many buttons and checkboxes.  This is a good time to introduce the second rule of Vulcan “When in doubt, accept the defaults.”

Mining plays the Villain

The vilification of mining is a frequent occurrence.  It is not uncommon to hear on the news or in general conversation that all the evils of the world can be blamed on mining.  Cinema often portrays the mining industry as the ‘boogey man’ in film.

I can’t deny that mining has a checkered past.  Some really bad things have happened at mines or because of mines, but current regulations have made mining a much safer place.  Other industries have similar histories of taking advantage of people or the land.  Why does mining seem to take the brunt of the negative publicity?

Many industries have used public advertising to promote their products as a whole.  You have heard these slogans before:
