Quartz osl dating

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating.It is useful to geologists and archaeologists who want to know when such an event occurred.Burdur city is located on a lacustrine sedimentary deposit at the northeastern end of the Fethiye–Burdur Fault Zone (FBFZ) in SW Turkey.Fault steps were formed in response to vertical displacement along normal fault zones in these deposits.Ages are in stratigraphic order assigning the formation of the studied deposits to the Last Interglacial stage.The p-IRIR dating was concluded to be a reliable technique for establishing precise and accurate chronologies and a trustworthy alternative to quartz optically stimulated luminescence (OSL) dating when the quartz luminescence characteristics are unsuitable.Optically stimulated luminescence (OSL) dating analysis has indicated an age ranging from 15,161 ± 744 to 17,434 ± 896 years for the liquefaction features.Assuming the groundwater level to be at critical depth, it was concluded that there was no possibility of liquefaction in most parts of the settlement during an earthquake.

The potential application of an elevated temperature p-IRIR SAR protocol developed by Thiel et al. Indeed, p-IRIR and published radiometric ages for Cyprus are in a good agreement. Published radiometric ages from the same site put additional significance on evaluating the effectiveness of p-IRIR dating, as independent age control on the latter remains scarce in literature to date.For this study, in order to investigate the relationship of sand and mud dykes with liquefaction, the present geologic and hydrogeologic environment, evolution of the host sediments and the paleoenvironment corresponding to duration of liquefaction were investigated.

Field work was carried out and laboratory experiments were performed on the samples taken from liquefied soils and clayey lacustrine sediments cut by sand and mud dykes.

Most luminescence dating methods rely on the assumption that the mineral grains were sufficiently "bleached" at the time of the event being dated.

  • Luminescence dating - Institut für Geologie - Universität Bern profil de paulette60


    The dating of sediments using the luminescence signal generated by optical stimulation OSL offers an independent dating tool, and is used most often on the commonly occurring minerals of quartz and feldspar and, as such, has proved particularly useful in situations devoid of the organic component used in radiocarbon.…

    Mar 26, 2017. Although there are still challenges e.g. relatively large uncertainties from insufficient luminescence sensitivity, overestimation caused by thermal transfer, and incomplete bleaching; Madsen and Murray, 2009, the quartz OSL dating using the SAR protocol has been successfully carried out to date young.…

    Sample exhibited significant thermal transfer. Nevertheless, three of the eight glacial successions in the upper Hunza valley were defined using quartz-luminescence. Although we discuss the possibility of inherited components in the CRN data, in terms of paleoclimatic interpretations both dating techniques give concordant.…

    Luminescence dating determines the age since burial of sediment by measuring the total amount of stored signal resulting from exposure of the sediment to a known annual dose of background radiation. The concept of luminescence dating relies on defects in the crystal lattice of dosimeter minerals, most commonly quartz.…
