Quartz OSL
Sediment burial questions, signal characterization, dose recovery, and protocol suitability.
Laboratory
Luminescence & Geochronology Laboratory
Planned OSL, IRSL, pIRIR, fading, dose-rate, and experimental volcanic-material workflows for research and teaching.
Overview
A cautious, staged development pathway
Routine quartz OSL and feldspar luminescence methods require controlled sampling, preparation, instrumentation, dose-rate assessment, protocol selection, and validation. Basalt-related luminescence is presented as feasibility and method-development research until performance is demonstrated against independently constrained samples.
Feldspar IRSL & pIRIR
Signal stability, residual dose, bleaching behavior, anomalous fading, and protocol comparison.
Basalt feasibility research
Experimental IRSL/pIRIR characterization of mineral fractions or associated materials—not routine basalt dating claims.
Dose-rate & uncertainty planning
Environmental context, radionuclide measurement strategy, water-content assumptions, and uncertainty budgets.
Method-development sequence
Before a dating service is offered
Characterize
Identify mineral fractions, signals, sensitivity, and measurement constraints.
Test
Evaluate bleaching, residuals, dose recovery, fading, and dose-response behavior.
Validate
Compare results against independently dated or tightly constrained samples.
Define scope
Publish exactly which materials, protocols, age ranges, and uncertainties are supported.
Next step
Discuss the depositional context before collecting a sample.
Luminescence projects can be compromised at collection, so early consultation matters.
