Dating of sediments and ceramics by quartz Optically Stimulated Luminescence (OSL) using the Single-Aliquot Regenerative-dose (SAR) protocol on multi-grain aliquots of sand or silt fractions. The service includes preparation of quartz concentrate, luminescence measurements for protocol optimization and validation (dose recovery tests), luminescence measurements for equivalent dose determination, sample preparation for dose rate assessment, high-resolution gamma spectrometry, data analysis, age calculation, and a technical report.
Dating of sediments by feldspar post-infrared infrared stimulated luminescence (pIRIR) using the Single-Aliquot Regenerative-dose (SAR) protocol on multi-grain aliquots of sand or silt fractions. The service includes preparation of potassium feldspar concentrate, luminescence measurements for protocol optimization and validation (dose recovery tests), luminescence measurements for equivalent dose determination, sample preparation for dose rate assessment, high-resolution gamma spectrometry, data analysis, age calculation, and a technical report.
Analysis of optically stimulated luminescence (OSL) and thermoluminescence (TL) sensitivity of polymineral and quartz aliquots of sand or silt fractions. The service includes preparation of grain concentrates, luminescence measurements, and data analysis for sensitivity determination. For polymineral aliquots, an IRSL/OSL mineralogical maturity index is also calculated.
