Geology Aluminum 26 Beryllium 10 Burial Age Calculator
Al26/Be10 ratio burial decay with explicit initial ratio and decay constants; assumes no postburial production, no inferred complex history. 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 paired aluminum-26/beryllium-10 burial model uses their different decay rates to interpret a ratio decrease.
A paired aluminum-26/beryllium-10 burial model uses their different decay rates to interpret a ratio decrease.1
Initial production ratio, shielding and post-burial production assumptions must be established before interpreting the conditional duration. Use this tool to calculate aluminum 26 beryllium 10 burial age from the supplied measurements and assumptions.
When to use Geology Aluminum 26 Beryllium 10 Burial Age Calculator
Use this tool to calculate aluminum 26 beryllium 10 burial age 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 Aluminum 26 Beryllium 10 Burial Age Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter initialAlBeRatio, measuredAlBeRatio, alDecayPerMa, beDecayPerMa, using the field meanings and rules below, then run the tool.
- Read simpleBurialAgeMa. 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 |
|---|---|---|---|
| initialAlBeRatio | Initial al be ratio | number | Required |
| measuredAlBeRatio | Measured al be ratio | number | Required |
| alDecayPerMa | Al decay per ma | number | Required |
| beDecayPerMa | Be decay per ma | number | Required |
Require positive initial and measured Al/Be ratios and positive decay constants per Ma. Require aluminum decay greater than beryllium decay and measured ratio no greater than initial ratio. Return ln(initial/measured)/(alLambda−beLambda) in Ma; equal ratios give zero. No production during burial or exposure sequence is modeled.
burialAgeMa=ln(initialAlBe/measuredAlBe)/(alDecayPerMa−beDecayPerMa) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| simpleBurialAgeMa | Simple Burial Age Ma; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Initial production ratio, shielding and post-burial production assumptions must be established before interpreting the conditional duration. 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.
