Luminescence Dating

2021
Luminescence dating is part of a suite of trapped charge dating techniques used in Quaternary research. It is a geochronological technique which provides absolute dating for geological events and archeological artifacts from the late Quaternary and, with a dateable age range between a few years and a few hundred thousand years, has become a broadly ...

Luminescence Dating Relevant to Human Origins

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1992
Abstract Luminescence dating provided the first direct and independent evidence that anatomically modern humans had a presence in western Asia earlier than is consistent with the ‘regional continuity’ model. The reliability of the result concerned, 92 ( ± 5) ka for burnt flints from Qafzeh Cave, is excellent and consistent with ...

Luminescence Dating Protocols and Dating Range

2013
Half a century after the publication of the first Thermoluminescence (TL) ages, the field of Luminescence Dating has reached a level of maturity. Both research and applications from all fields of archaeological science, from archaeological materials to anthropology and geoarchaeology, now routinely employ luminescence dating.

Luminescence Dating, Uncertainties and Age Range

2014
Luminescence ages have an uncertainty of at least 4–5 %, mainly due to systematic errors in both dose rate (conversion factors) and equivalent dose (source calibration) estimation. In most cases, the uncertainty will be higher, due to random errors (e.g., spread in equivalent doses) or uncertainty in assumptions (e.g., water content fluctuations ...

Dating the Quaternary: progress in luminescence dating of sediments

Quaternary Science Reviews, 2006
Abstract Luminescence dating comprises a collection of numerical-age techniques that are among the most significant chronological tools currently used in Quaternary research. This paper briefly reviews the key historical developments in luminescence dating, from its roots in thermoluminescence dating of heated minerals to the development of optical ...

Luminescence dating at Katanda — a reassessment

Quaternary Science Reviews, 2001
Abstract A luminescence date of 80 ka for sediments associated with bone harpoon points recovered at Katanda in East Africa has been reassessed using additional samples. An original problem with radiation quenching has been overcome by using a higher preheat. Single-aliquot analyses suggest sufficient bleaching.
