On the other hand, archaeological data can sometimes be used to verify luminescence data, e.g. It accumulates again as soon as the minerals are buried by sediment and are thus protected from light. in the selection of the appropriate model for palaeodose determination in single grain OSL dating. The age formula, therefore, is straight forward and simple: age (a) = P(Gy) • D(Gy⋅a −1 ) = P • • • Dinternal Dexternal Dexternal where the paleodose (P, also termed equivalent dose (DE) or dose equivalent (ED) is expressed in Gy and • the various dose rates ( D ) in µGy/a. This paper is organized by material and question, rather than by time period, and in some examples more than one method was applied for a given site, which is a good way to check the consistency, especially of related dating methods. It is therefore essential to understand the influence of these parameters on the age results and establish strategies for their accurate determination. For example, sediments from sites should not be removed completely in order to allow the measurement of the external dose rates. 2002: Serge Occhietti/Jean-Paul Raynal/Pierre Pichet, Aminostratigraphy of Pleistocene and Holocene littoral deposits, Casablanca, Morocco, and correlation with the Mediterranean palaeoshorelines. An accurate and high precision comparison to radiocarbon dating is limited to the dendro-calibrated range of 14C to about 12 ka2, but possible for the entire 14C range at a lower resolution, which is quite similar to the precision obtained by luminescence dating3. This radiation originates • • • from the sample itself ( Dinternal ), the surrounding sediment ( D external ), and cosmic radiation ( Dcosmic ).

This should be taken into consideration by the archaeologist and may result in a different strategy of excavating a site. As with any other dating method it is important to define the relationships of a sample to be dated and its context in an archaeological site. Science and archaeological dating ceramics, 000 years.
