Optical dating of sediments
Optically Stimulated Luminescence (OSL) Dating is an estimation of the last time sediment or rock was exposed to sunlight (i.e., the burial age). It immediately gained the attention of the media and researchers around the world.Optical dating is a technique that was invented in the Physics Department at Simon Fraser University in the mid-1980s by Prof. This BC-invented technique has revolutionized earth sciences and archaeology in that we can now derive absolute ages for climate-sensitive sedimentary landforms (e.g.He has succeeded in doing so for those who may have only a minimal background in physics.It would be unwise for anyone in archeology to consider optical dating methods without consulting this book.
But in fact, samples from different depositional environments may have different bleaching characteristic.
This is potentially one of the most powerful dating techniques available to the geoarchaeologist.
This method has developed slowly since 1985, and much about it is explained in clear . Although new retired from active research, he has provided for the lay reader a thorough review of the most important recent advance in the field; the use of photon-stimulated luminescence for dating Quaternary sediments, or optical dating.
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.
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.
