What is luminescence dating

Luminescence dating is an absolute radiometric method of determining the age of a material since a key event in its history - typically burial (in the case of sediments) or firing (in the case of ceramics or burnt stone).When a geological sediment is buried, the effects of the incoming solar radiation are removed.Written by some of the foremost experts in luminescence dating from around the world, this book takes a new approach.

Using quartz or feldspar minerals found in almost ubiquitous sand and finer sediments, luminescence can provide ages from over 500,000 years ago to modern.

This allows researchers to date materials that cannot be dated using other techniques (e.g., lack of suitable organic remains for radiocarbon dating).

Additionally, since it is capable of directly dating cultural materials such as ceramics, the bridging arguments between dating events and target events are minimized.

The book helps scientists plan where and what to sample to optimise the successful application of luminescence and stemming from that the chronologies that can be constructed.

The sets out the challenges and limitations when applying luminescence dating in different environmental and archaeological settings and gives practical advice on how issues might be avoided in sampling, or mitigated by requesting different laboratory measurement approaches or analysis.Given an estimate of the rate of received ionizing radiation (the dose rate, or D), and knowing the total accumulated dose (the palaeodose; designated D This accumulated signal results in luminescence (i.e.
