Geology Th U Ratio Calculator
Actual same-basis thorium/uranium ratio, not radioactive age or equilibrium decay status. Actual independently matched quantities/units required; not infer causal effect, clinical guidance or safe design.
Description
A thorium-to-uranium ratio compares concentrations on the same basis.
A thorium-to-uranium ratio compares concentrations on the same basis.1
It is a composition measure rather than an age calculation. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Geology Th U Ratio 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 Th U Ratio Calculator and understand its results
- Establish the sample and coordinate basis, matching units, calibration source and applicable model assumptions.
- Enter actualThoriumConcentration, matchedUraniumConcentration, using the field meanings and rules below, then run the tool.
- Read result.observedRatio. 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 |
|---|---|---|---|
| actualThoriumConcentration | Actual thorium concentration | number | Required |
| matchedUraniumConcentration | Matched uranium concentration | number | Required |
Require nonnegative actualThoriumConcentration and positive matchedUraniumConcentration. Divide numerator by denominator without percent scaling. Values need not be integers and the tool does not require numerator≤denominator or clamp the result. Establish matching measurement scope and units independently.
result=1×actualThoriumConcentration/matchedUraniumConcentration 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.observedRatio | Numerator divided by denominator with the scaling and units documented above | number |

}Limitations and assumptions
It is a composition measure rather than an age calculation. 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.
