Quartz optically stimulated luminescence (OSL) dating is widely used to determine the time of deposition and burial of Late Quaternary sediments.Application of the method is usually limited to the past 150,000 years due to early saturation of the OSL signal.The first part of the book presents basic notions and introduces the standard techniques, along with several illustrative case histories. Review: "Many techniques have been developed to obtain chronometric dates . Aitken wrote this book both for practitioners who lack training in physics and for users.The book then proceeds to discuss the limitations of the technique and the factors affecting reliability. Until geologists and archaeologists gain enough knowledge to evaluate the product, luminescence dating will not get the widespread application it deserves.
Uranium-series uses the decay of uranium and thorium isotopes (Th) in calcites in particular, such as stalactites and stalagmites in caves.Written by one of the foremost experts on optical dating, this book aims to bring together in a coherent whole the various strands of research that are ongoing in the area. Thermoluminescence (TL) and electron spin resonance (ESR) methods have been important in dating heated stone tools and buried tooth enamel, especially in the context of early modern humans and Neanderthals during the last few hundred thousand years.It gives beginners an introduction to the technique while providing experienced practitioners with a valuable source of up-to-date references. This rather technical book is designed almost as a manual for the extraction and evaluation of dates by the method usually known as OSL (optically stimulated luminescence), an approach similar to TL but applied to sediment grains, usually sand or loessic silt, younger than about half a million years in age. fashion by Aitken."--"If anyone can be considered the father of luminescence dating, it is Martin Aitken.Many methods are only useful for a limited period of time (for radiocarbon, for example, 40,000 years is the maximum age possible).Scientists dating Quaternary glacial sediments in Antarctica most commonly use one of the methods outlined below, depending on what kind of material they want to date and how old it is.
