Developing Realistic 3-D Models

Jul 07, 2015

Realistic and accurate 3-D geological models are a powerful communication medium that provide insight and a rapid understanding into the makeup of any economic deposit.  Understanding the complete 3-D geology of the deposit is of the highest priority, with subsequent business development decisions based entirely on these key understandings.  Thus, it is of utmost importance that the starting model is accurately and reasonably mapped in 3-dimensions.  Current 3-D modelling practices do not account for nor are able to integrate the entire range of available data (Geochemical, Geophysical or Structural) thus are unable to deliver the required total geological detail for informed decision making.

Exploring for resources undercover is an expensive and complex exercise requiring a sound understanding of the expected or ‘most-likely’ geology to be encountered.  Conventionally, uncertainty within the geology model is addressed utilising the available drilling data almost exclusively to develop a sub-surface 3-D perspective.  This method is associated with significant risk however this can be mitigated through the introduction of a geometric frame of reference, ascertained through the application of structural geology principles in order to constrain the likely overall geometric geological framework.  Thus in the pursuit for developing realistic and representative 3-D geological models for the purpose of exploration, adherence to fundamental key-principles in structural geology are critical for Exploration Success.  Model Earth Pty Ltd has developed an innovative approach to constructing achievable geologically predictive products that have successfully been utilised for exploration strategy development.  Like any good 2-D geology map, the 3-D geological model should tell a story...
