Faults are not supported with Kriging in Surfer 8 and higher versions. In older versions of Surfer, Kriging with faults caused an error (The system of Kriging equations is singular) due to the discontinuity along the fault, and this feature was removed from Surfer 8.
Use one of the other gridding methods that supports faults, as listed in the Breaklines and Faults topic:
- Inverse Distance to a Power
- Minimum Curvature
- Nearest Neighbor
- Data Metrics
Minimum Curvature produces a very similar result to Kriging, so we suggest you start with that method.
