Luminescence Dating: A Review and a Perspective for Arid Zone Sediments
Year: 2016
Type: review
Abstract: Luminescence dating, which relates to absorption of nuclear energy by natural minerals and emission of luminescence on thermal or optical excitation. has advanced significantly during the last few decades and offers excellent scope for dating various arid zone sediments of 100-150 thousand years age with greater conviction. Aeolian sediments provide less complications in dosimetric calculations and are easier to date than the fluvial sediments and pedogenic carbonates, which have more complex dosirmetric problems. The experimental procedu!'es and analytical aspects of thermoluminescence and optically stimulated luminescence dating have been discussed here, and the need for further research to understand the basic physical processes which give rise to mineral luminescence as well as variations in age estimation, have been highlighted. Inspite of the need for refinement in technique, the dates so far on a large number of samples from aeolian and othcr stratigraphic sequences have helped to establish the late Quaternary geochronology of the arid lands.
