Abstract

The thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) dating of crystalline materials, first applied to calcites (limestone buildings), has been extended to carved megalithic monuments made of granites, basalt and sandstones derived from archaeological sites. Various applied criteria for potential dating included pulsed blue light stimulation, different preheating and solar simulator bleaching, while the single (and multiple) aliquot regeneration and additive dose procedures were used for equivalent dose determination. The decay curves of signal loss follow a power law, n-p; for blue stimulation the signal loss of quartz and feldspar is better approached by an exponential law, 1-aln(n).
