Fanglomerate dose rate analyses by means of ICP -AES/-MS and high-resolution gamma spectrometry illustrate homogeneous environment for the 2 mm proportions of the samples; however, the 2mm proportions are indicative of dose rate heterogeneity probably due to different lithologies.Our results from twelve samples indicate that alluvial fan formation in the Coachella Valley happened during both glacial periods and transition from glacial to interglacial periods.
The present contribution reviews the physical basis, mechanisms and methodological aspects of luminescence dating; discusses advances in instrumentations and facilities, improvements in analytical procedures, and statistical treatment of data along with some examples of applications across continents, covering all periods (Middle Palaeolithic to Medieval) and both Old and New World archaeology.
They also include interdisciplinary applications that contribute to palaeo-landscape reconstruction.
Praise from the reviews: "This book is a must for any Quaternary scientist." SOUTHAFRICAN GEOGRAPHICAL JOURNAL, September 2006 “…very well organized, clearly andstraightforwardly written and provides a good overview on the widefield of Quaternary dating methods…” JOURNALOF QUATERNARY SCIENCE, January 2007 Since World War II, there has been tremendous success in the development of new methods for dating artifacts; the so-called `radiocarbon revolution' was only the first such discovery.
The increasing accuracy of the various new techniques has brought about major changes in archaeological research strategies.
On the other hand, there is a possibility that the slip rate along the Mission Creek fault has slowed from the Biskra Palms toward the northwest and the slip might then have been transferred to the Banning fault.
The aim of this book is to give readers a broad review of topical worldwide advancements in theoretical and experimental facts, instrumentation and practical applications erudite by luminescent materials and their prospects in dealing with different types of luminescence like photoluminescence, electroluminescence, thermo-luminescence, triboluminescence, bioluminescence design and applications.
For events occurring over Late Quaternary timescales, optically stimulated luminescence (OSL) dating is a chronological method that can be used in these settings; however, current OSL approaches are only suited to the fine sand deposits which are present as layers or lenses in the fan architecture.
The problem with this sampling approach is that in many fan exposures such deposits are rare, limiting the applicability of OSL.
In this study we have investigated the feasibility of a luminescence method for dating fanglomerates by sampling the coarse fraction and extracting the fine sand matrix for dating.
