Geology Flexural Slip Restoration Calculator
Concentric flexural-slip h×signed bend radians across independently matched adjacent beds; orientation and slip sign retained. 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
Flexural slip relates bed separation and rotation to an idealized relative displacement.
Flexural slip relates bed separation and rotation to an idealized relative displacement.1
Keeping rotation signed preserves the direction of the inferred slip under the caller's geometry convention. Use this tool to calculate flexural slip restoration from the supplied measurements and assumptions.
When to use Geology Flexural Slip Restoration Calculator
Use this tool to calculate flexural slip restoration 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 Flexural Slip Restoration Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter adjacentBedNormalSpacingsM, observedBendAnglesRadians, using the field meanings and rules below, then run the tool.
- Read signedFlexuralSlipsM. 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 |
|---|---|---|---|
| adjacentBedNormalSpacingsM | Adjacent bed normal spacings m | list of number | Required |
| observedBendAnglesRadians | Observed bend angles radians | list of number | Required |
Enter nonempty aligned positive bed-normal spacings and signed bend angles with absolute value no greater than π. Multiply each spacing by its angle in radians to return signed slip in meters. No angle conversion or fold geometry reconstruction is performed.
slipM_i=bedSpacingM_i×bendAngleRadians_i Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| signedFlexuralSlipsM | Signed Flexural Slips M; follow the units, sign, ordering and evidence convention stated above | list of number |

}Limitations and assumptions
Keeping rotation signed preserves the direction of the inferred slip under the caller's geometry convention. 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.
