GOCAD® Mining Suite

Sparse Module – Structural Geology Tools
Earth modelling and 3D-GIS solutions for mineral exploration
Summary
The GOCAD Mining Suite Sparse Module was developed incollaboration with the Geological Survey of Canada to address
the problem of constructing 3D structural geology models
given sparse structural data. It provides the user with the tools
needed to quickly build smooth 3D curves and surfaces that
represent their structural data while maintaining the freedom
to use the GOCAD Mining Suite editing and interpolation tools.
GOCAD Mining Suite Sparse Module is an extension ofParadigm™ GOCAD, the world's most sophisticatedgeological modelling platform, adapted specifically for themining industry with mining modules available exclusively
from Mira Geoscience.

Structural data interpretation tools thatinteractively and automatically create 3D
earth models» Facilitates construction of faults, lithologicalcontacts and closed bodies» Model smooth surfaces and curves by using grip framesthat can be manipulated in 2D or 3D - grip frame
construction can be carried out as part of 2D section
interpretation* GOCAD® is a registered trademark of Paradigm™

» Edit and interpolate sparse surfaces using the Mining
Suite tools» Incorporate surface , drillhole and undergroundmeasurements» Create 3D geology models from surface mapping only

NEW extension: 3D Structural Fields Interpolator» Provides first-pass interpretation of fold closures andplunge» Supports bedding and foliation input data

Task pane interface» Intuitive layout» Create/Edit grip frame» Interpret surface/curves» Transfer structural measurements

Structural Fields Interpolator» Interpolates 3D plunge and structural fields
in form lines or block models from raw
oriented data
» Overcomes the complexity of rock geometry
interpretation» Incorporates facing direction into theinterpolation» Models the geometric behaviour of structuralelements in 3D using point data
» Views the structural fields as streamlines frompoint data or as a voxet property» Compatible with 2D sections to assist traditional
section interpretation

Interpretation tools

Grip frames» Create by digitising from existing curves, map
traces and points» Digitise on 2D sections» Insert between grip frame lines or at the end ofthe grip frame» Edit like regular GOCAD curve objects» Fit to points» Extend» Snap to map trace

Map traces» Estimate strike and dip from geometry» Transfer structural information and interpolate
along trace» Project surface from interpolated structure» Project grip frame from interpolated structure

Structural measurements» Uses GOCAD Mining Suite Structural Graphics» Transfer from points to map trace» Transfer from map trace to grip frame» Grip frame (free form) to surface or closed body
» Map trace» Map trace and keel
» Return curves or surfaces» Control mesh density» Edit/Update

Parametric interpolators» NURBS» Bezier» Hybrid

Sticky planes» Constraint grip frame to section plane» Can be turned on and off© 2011 Department of Natural Resources Canada. All rights reserved...Montreal Vancouver Brisbane Perthwww.MiraGeoscience.com@MiraGeoscience
