Geology Paleomagnetic Inclination To Paleolatitude Calculator
Ideal GADtanI=2tanλpaleolatitude signed branch, actual independently corrected inclination. Hemisphere/reversal convention, flattening, tectonic rotation and nondipole field external; not full pole position.
Description
Inclination can be related to paleolatitude under a geocentric axial-dipole assumption.
Inclination can be related to paleolatitude under a geocentric axial-dipole assumption.1
Corrections for the actual magnetic record precede this conditional transformation. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Geology Paleomagnetic Inclination To Paleolatitude Calculator
Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the sample and coordinate basis, matching units, calibration source and applicable model assumptions.
How to use Geology Paleomagnetic Inclination To Paleolatitude Calculator and understand its results
- Establish the sample and coordinate basis, matching units, calibration source and applicable model assumptions.
- Enter actualIndependentlyCorrectedInclinationDegrees, using the field meanings and rules below, then run the tool.
- Read result.conditionalGeocentricAxialDipolePaleolatitudeDegrees. Interpret each field using the units, signs and evidence rules below.
- If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualIndependentlyCorrectedInclinationDegrees | Actual independently corrected inclination degrees | number | Required |
Require signed inclination between −90 and 90 degrees inclusive. Convert to radians, compute atan(0.5×tan(inclination)) and convert to degrees. The endpoint calculations use the runtime trigonometric implementation. No tilt correction, field reconstruction or pole coordinates are computed.
conditionalLatitudeDegrees=(180/pi)×atan(0.5×tan(inclinationDegrees×pi/180)) Apply the field units and exact ordering, boundary and evidence rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result containing the calculation or selected reference fields below | object |
| result.conditionalGeocentricAxialDipolePaleolatitudeDegrees | Conditional Geocentric Axial Dipole Paleolatitude Degrees; use the units, sign convention and calculation stated above | number |

}Limitations and assumptions
Corrections for the actual magnetic record precede this conditional transformation. Results depend on the independently established measurement basis and the exact model assumptions above.
Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
