Thermoluminescence dating of ocean sediments


To circumvent this problem, a partial bleach PB technique was proposed. We describe here the experimental evidence which indicates that some event which has the same result does occur. Thermoluminescence TL is the light emitted by a material when heated and which results from a previous dose of radiation. These features suggest a model based on the quantum mechanical effect of tunneling. Since the first application of TL dating, the relevant role and the characteristics of anomalous fading were highlighted [Wintle and Huntley, ]: The as- sumption is that the TL signal consists of different components, some of which can be optically reset by seconds or minutes of solar exposure, whereas others require solar bleaching times several orders of magni- tude greater. The use of TL to date the deposition of ocean sediments which we propose here is similar in the main principle except for the lack of the heating event. The TL age uncertainty is primarily set by the uncertainty in the water content. Subsequent radiation from radionuclides in the sediment increases the TL and this increase is used for dating.
