Lithology Filtering Options

Menu Options

Limit Input to Selected G Values: Check this box if you want to omit specific lithology types from the modeling process. This is a pre-modeling data filter. Expand this heading to enter the limits. (See image below.)
- Minimum G-Value: Enter here the minimum "G" value to be included in the modeling process. The G values for your lithology materials are defined in the Lithology Types Table.
- Maximum G-Value: Enter here the maximum "G" value to be included in the modeling process.
Limit Model to Selected G Values: Check this box if you want to omit specific lithology types from the output model. This is a post-modeling value filter, whereby nodes outside the selected G value range are changed to null after interpolation. Expand this heading to enter the limits.
- Minimum G-Value: Enter here the minimum "G" value to be included in the output model.
- Maximum G-Value: Enter here the maximum "G" value to be included in the output model.
Compare the following diagrams. The first is a lithology model with neither of the above limits enforced. The middle image is an example of the model which results from the Limit Input filter, with Clay, Siltstone, and Soil excluded from the modeling process. The right-hand image is the model which results from the Limit Model filter, with Clay, Siltstone, and Soil removed from the model after it was interpolated (note the holes).
