K-MINE Fault Modeling: Fast and Accurate Fault Frameworks

Overview of the Fault System Modeling Feature

The new Fault System Modeling tool in K-MINE enables fast and accurate creation of fault framework models for structural geology and deposit interpretation. Users can build complete fault systems, assign geological parameters, and generate solids that serve as boundaries for further geological modeling.

Mapping Fault Traces and Building 3D Geometry

On the map, several fault traces appear at surface level with known dip and strike parameters. These traces can be drawn in plan view and projected onto a selected surface to automatically assign accurate Z-coordinates. This process forms the base geometry required to construct 3D geological structures.

Automated Fault Setup and Parameter Input

Within the Fault System Modeling task, users can load a prepared list of faults and define key parameters, including Azimuth and Dip. The tool also allows applying top constraints such as topography or any other limiting surface. When no upper surface is defined, the modeling operates within the project’s global boundaries.

Configuring Relationships Between Faults

The order of faults in the table is important because it defines how solids will be generated. Each fault can be linked to neighboring structures by selecting an appropriate interaction type. When relationships are specified, K-MINE automatically creates structural blocks between faults. These solids can later be used as boundaries for modeling ore bodies, lithological domains, or other geological units.

If no relationships are set, the system defaults to dividing the modeling volume into two solids based on the first listed fault. For example, when Fault 1 is the primary element, a blue solid appears north of it and a brown solid appears south of it.

Example of Structural Relationships

To illustrate, define a connection between two sub-meridional faults: Fault 2 and Fault 1. Choose the Joining interaction, indicating that Fault 2 connects to Fault 1 from the south. As a result, the block south of Fault 1 is split into two solids to the east and west of Fault 2.

A sub-latitudinal structure, Fault 4, intersects the same zone. Define that Fault 4 joins Fault 1 from the south and Fault 2 from the west. This interaction produces five solids across the fault system: one block north of Fault 1, one south of Fault 4, two southeast of Fault 2, and one triangular block enclosed by Fault 1, Fault 2, and Fault 4.

Improving Geological Interpretation with K-MINE

The Fault System Modeling feature significantly enhances structural modeling workflows, helping geologists build reliable fault frameworks, improve interpretation accuracy, and save valuable time during deposit evaluation.
