Luminescence dating guidelines on using luminescence dating in archaeology

More information
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. With this bleaching effect removed, the influence, albeit often weak, of naturally-occurring radioactive elements primarily potassium, uranium and thorium within the sediment together with incoming cosmic rays results in the accumulation of a signal within individual mineral grains most commonly quartz and feldspars. It is this signal that is the key to luminescence dating techniques.

Luminescence Dating - Guidelines on using luminescence dating in archaeology | Antiques & Baijiu

Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology. The technique is particularly useful for dating materials ranging in age from a few decades to around ,—, years. In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed. This is followed by a look at measurement equipment that is employed in determining age and its operation.

Thermoluminescence dating

Thermoluminescence dating TL is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated lava , ceramics or exposed to sunlight sediments. As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating.

Luminescence dating is now widely applied by scientists working in Quaternary geology and archaeology to obtain ages for events as diverse as past earthquakes, desertification and cave occupation sites. Using quartz or feldspar minerals found in almost ubiquitous sand and finer sediments, luminescence can provide ages from over , years ago to modern. Written by some of the foremost experts in luminescence dating from around the world, this book takes a new approach. It is accordingly for scientists who require luminescence ages for their research rather than those scientists developing the luminescence technique or making their own luminescence measurements. The background to the technique is explained in simple terms so that the range of potential applications, limits and issues can be understood.
