Process, map, QA and interpret your ground and airborne survey geophysics, geochemistry, and geology.

Performance Improvements

64-bit applications

Oasis montaj and Target are now 64-bit applications. As 64-bit applications, they are now able to access to all available memory on your system, providing more efficient processing, improved performance, and the ability to create and work with much larger databases, voxels, and grids.

Wireframing

A new digitization workflow for creating geological interpretations.

A new streamlined workflow makes it easy to digitize geological interpretations on section and plan maps. Polygon features can be used to represent individual rock units, alteration or mineralization zones, while polyline features can be used to draw faults or contact surfaces.

A single geostring file can contain a number of interpretations stored as geological features. Using a single geostring file to store all the interpretations for a drillhole project makes it easy to manage your interpretations and share them with others.

Improved snapping for new digitization workflow

When digitizing, you can now snap to the true X, Y, Z drillhole data locations, or to the points that are projected on the section plane. This provides you with more flexibility and control when digitizing interpretations, which leads to more realistic and accurate interpretations. Discover the new digitizing and wireframing tools for 3D subsurface modelling in Oasis montaj and Target 9.0

Build wireframes from section interpretations

Geosoft provides an easy-to-use wireframing interface that enables you to build 3D subsurface geological models by joining section and plan map interpretations stored in Geosoft string files. Simply click on the features you want to include and a wireframe model is created from the shapes. Polygon features form closed surfaces or bodies and polyline features create open surfaces. Flat, conical or rounded ends can be used to close the open ends of a wireframed polygon feature.

After saving the wireframe to a Geosoft surface (geosurface) file, the total surface area is reported for open surfaces and total volume is reported for closed bodies. Closed geosurfaces can be used in voxel math expressions to clip voxels or to create constraints to use in inversions. Collaborate on 3D modelling projects by sharing the interpretations as Geosoft string files or the wireframing results as Geosoft geosurface files.

Voxel math expressions using closed 3D geosurfaces

You can now use closed 3D surfaces from wireframing as variables in voxel math expressions, enabling you to clip voxels to the inner or outer edges of a 3D surface.

There are a number of ways you can use this functionality. For example, you can clip voxels to a closed surface to calculate an average grade within a specific rock unit or you can assign a constant value to the voxel cells inside or outside the closed surface, which makes it much easier to create constraints for VOXI.

Gravity and Terrain Correction

Added a new moving platform gravity workflow for processing shipborne gravity survey data. This new workflow supports additional gravity and bathymetry imports, including MGS-6 and P1/90 formats and includes updated survey path corrections.

UXO Land

UXO Land is a new extension for Oasis montaj that provides a complete suite of tools for working with land-based UXO survey data. UXO Land combines the features previously available in UX-Detect and UX-Process into a single workflow that takes you through all the steps from survey planning to target identification and remediation.
