Encom QuickMag
Fast, realistic and advanced 3D magnetic geology mapping
A high performance, 3D user-guided inversion package that is easy to learn, fast to use and provides advanced capabilities for generating geological interpretations from gridded magnetic field data.
Work More Efficiently!
Encom QuickMag allows the construction of reliable geological models of magnetic anomalies in a fraction of the time of manual methods. Simply point at an anomaly, choose a geological style and in seconds QuickMag will automatically construct a 3D model of the magnetic source.
On a standard desktop computer QuickMag builds realistic 3D geological models in less than 5 seconds and a full inversion in less than 60 seconds.
Fast, Realistic Modelling
QuickMag is based on an automatic geological modelling technique which maps the distribution of magnetic material across an unconformity surface. The initial automated ‘Quick Match’ process builds a starting model for inversion which QuickMag then refines through its advanced regularised inversion technology. QuickMag optimises time by performing the model interpretation directly from the image view of the data.
Depth Mapping
Map the depth of cover for intrusions, dykes and folded bedding using flexible 3D geological models that are built automatically. QuickMag will simultaneously allow the mapping of geological boundaries, magnetic susceptibility and dip with options to explore changes along the geological trend.
Remanence Mapping
The all new resultant magnetisation estimation tool detects remanent magnetic events at sensitivities not previously possible. Magnetisation departure angles as small as 10 degrees can be detected, allowing the fresh investigation of historical surveys, allowing users to look for signs of alteration events or interpret differences in timing of intrusive events.

More Powerful, More Automated
Encom QuickMag is a fresh approach to magnetic anomaly interpretation. This powerful modelling system utilises expert systems research to hide much of the complexity involved in 3D magnetic modelling.
By reducing the number of manual steps required to analyse a magnetic source, the time that a typical 3D modelling exercise takes has been dramatically reduced.

Depth, Structure, Lithology & Remanence Interpretation
- Quality depth determinations from magnetic data require an appropriate, constraining geological model, or estimation errors may exceed 50% of the true depth. With QuickMag you can easily select a suitable geological model style or test a range of models to determine the best match. Depth information from magnetic data is useful in: diamond exploration, mineral exploration, petroleum exploration, coal mining, overburden studies, landfill and unexploded bomb location.
- Structural information derived from QuickMag is used to distinguish between synclines and anticlines, map vertical and lateral fault throws, estimate dip and dip change and axial depth changes. QuickMag is sensitive to dip changes along strike for individual models and can be used to detect structural distortions that may not be obvious in the magnetic images. Fault throws are estimated from depth changes along the model axis.
- Magnetic susceptibility is an important physical property of rocks and within limited geological domains can be used to identify the probable rock type or formation. Because QuickMag builds realistic solid 3D geological models for each magnetic anomaly allowing the magnetic susceptibilities to reflect robust volume averages of the target properties. Axial magnetic susceptibility variations for a specific model may reflect alteration events that have modified the properties. This technique is limited to shallow bodies or dyke-like bodies where the thickness is expected to be constant.
- The influence of remanence is present in most magnetic anomalies but has been difficult to detect except for magnetic reversals. QuickMag now provides a tool for direct estimation of the resultant magnetisation vector which is the vector sum of the induced and remanent magnetic fields. QuickMag uses the magnetic moment method to derive the resultant magnetisation vector from which you can compute the total departure angle as a first order indicator of remanence. This sensitive tool allows QuickMag to map small total departure angles and detect previously undetected subtle remanence events.
Dynamic Interface
The QuickMag interface is displayed in a template composed of linked active objects that deliver dynamic information on the progress of interpretations. Create high quality presentations of interpretations from a library of templates which can be customised for individual needs. The active objects include:
Image Maps
The image map object controls contours, colour LUT selection, image illumination and shading direction, model attributes and titles. Dynamic pan, zoom and zoom dependent colour stretching provides full scale focus on any magnetic anomaly within a complete survey. QuickMag supports a large range of industry standard grid formats.
Cross-section
Model cross-sections and magnetic data profiles provide visual feedback on data mismatches. The computed first vertical derivative and regional magnetic fields are superimposed on the total magnetic field curves to increase sensitivity and comprehension of the inversion results.
Block Model Spreadsheet
The primary attributes of each block in the geological model are summarised in the block model spreadsheet. Spreadsheet columns include depth, width, dip, position and other optional attributes.
Quality Report
The quality report provides quantitative estimates of the quality of factors that influence the geological model interpretation such as the regional magnetic field, noise from shallow geological sources, adjacent anomaly overlap and inversion RMS match.
3D Model Display
Interactive 3D displays provide a useful presentation of complex models that may not be easily visualised in a map or limited number of cross-sections.
Titleblocks
Standard templates can be modified to include personalised details and logos, and saved for re-use at a later time.
Pan & Zoom Tools
QuickMag uses data and page navigation tools. The data zoom and pan allows the positioning of a map view over a magnetic anomaly while the page zoom allows the printed page to be viewed at high resolution.
Control Panel
QuickMag provides a comprehensive control panel to define the geological style in terms of depth, susceptibility width, position and dip shapes. Known values such as susceptibility and clamp parameters can be inserted during inversion.
