Modeling Using Perimeters

A geological interpretation consists of section or plan drawings showing structure and mineral boundaries. These can be created directly within Datamine Studio using drillhole information and interactive graphics or by hand over hardcopy plots which you can later digitize.

As you digitize strings you should assign them codes or attributes to distinguish the different zones and rocktypes. Datamine can later assign these attributes to the cells created in the block model. Examples of attribute fields include Color, ZONE or Rocktype, or any other item you find necessary to describe the geology.

Using interactive graphics, perimeter points can be placed at the precise three-dimensional coordinates of selected drillhole intervals. DATAMINE calls this automatic positioning of points on existing screen objects snapping. For Datamine to fill the strings with cells they must form closed areas or perimeters. Ensure that adjacent boundaries abut up against each other with no gaps or overlaps. You can use interactive string utilities to automatically generate outlines from open overlapping strings. In this way common boundaries need to be digitized only once.
