Geology Fault Gouge Thickness Calculator
Actual mapped normal traverse, left-interval gouge flags; caller distinguishes observed segments from unobserved geological continuation. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
A gouge thickness can be estimated from intervals along a fault-normal traverse already classified as gouge.
A gouge thickness can be estimated from intervals along a fault-normal traverse already classified as gouge.1
Sample coordinates and interval flags must describe the same direction and resolution for the summed thickness to be meaningful. Use this tool to calculate fault gouge thickness from the supplied measurements and assumptions.
When to use Geology Fault Gouge Thickness Calculator
Use this tool to calculate fault gouge thickness from the supplied measurements and assumptions. Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
How to use Geology Fault Gouge Thickness Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter observedNormalTraverseM, gougeFlags, using the field meanings and rules below, then run the tool.
- Read observedGougeThicknessM. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedNormalTraverseM | Observed normal traverse m | list of number | Required |
| gougeFlags | Gouge flags; binary 0/1 under the definitions below | list of number | Required |
Enter at least two strictly increasing fault-normal coordinates and an aligned binary gouge-flag list. For each interval use the flag at its left endpoint; add its coordinate span when that flag is 1. The final flag is validated but has no following interval and contributes no thickness.
gougeThickness=Σ_(i=0..n−2) flag_i×(coordinate_(i+1)−coordinate_i) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| observedGougeThicknessM | Observed Gouge Thickness M; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Sample coordinates and interval flags must describe the same direction and resolution for the summed thickness to be meaningful. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
