Geology Vitrinite Reflectance Ro Calculator
Actual standard-calibrated reflected intensities for independently identified vitrinite in same optical medium; no maturation identity or universal grade. 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
Vitrinite reflectance compares measured optical response with a laboratory calibration.
Vitrinite reflectance compares measured optical response with a laboratory calibration.1
Instrument intensity becomes a reflectance value only through a suitably matched calibration and specimen preparation protocol. Use this tool to calculate vitrinite reflectance ro from the supplied measurements and assumptions.
When to use Geology Vitrinite Reflectance Ro Calculator
Use this tool to calculate vitrinite reflectance ro 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 Vitrinite Reflectance Ro Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter measuredStandardIntensities, callerStandardReflectancePercents, observedVitriniteIntensities, using the field meanings and rules below, then run the tool.
- Read calibratedRoPercents, meanRoPercent. 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 |
|---|---|---|---|
| measuredStandardIntensities | Measured standard intensities | list of number | Required |
| callerStandardReflectancePercents | Caller standard reflectance percents | list of number | Required |
| observedVitriniteIntensities | Observed vitrinite intensities | list of number | Required |
Enter aligned standard intensities and reflectance percentages, with at least two strictly increasing intensity knots. Interpolate each observed intensity within the calibration endpoints and require every resulting reflectance to be nonnegative. Return the individual reflectance percentages and their arithmetic mean; at least one observation is needed for a finite mean. Response knots need not be monotonic, and the tool does not correct preparation or instrument effects.
Ro_i=linearInterpolate(standardIntensity,standardRoPercent,observedIntensity_i); meanRo=mean(Ro_i) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| calibratedRoPercents | Calibrated Ro Percents; follow the units, sign, ordering and evidence convention stated above | list of number |
| meanRoPercent | Mean Ro Percent; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Instrument intensity becomes a reflectance value only through a suitably matched calibration and specimen preparation protocol. 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.
