Fission-Track Dating, at a known rate, the age of a mineral or glass can be calculated from the amount of uranium and number of spontaneous fission tracks it contains. Zircon and glass are the most suitable materials for dating archaeological samples and Quaternary deposits by the fission-track method. Zircon has been c

Uranium Series Dating,y. The growth of these isotopes in naturally occurring materials at archaeological sites can be used to determine the age of sites. The growth of .Th from its parent, .U, can be used over a time range from a few hundred to half a million years. Calcite precipitated from running or dripping water in

Luminescence Dating,sions of luminescence dating to other fired materials such as burnt flint, and to stalagmitic calcite and unburnt sediment are then outlined, including optical dating of the latter. Final sections deal with limitations in age range, accuracy and error limits.

Archaeomagnetic Dating,d archaeointensity dating are regional pattern-matching techniques, whereas magnetic reversal dating is a global pattern-matching method. Secular variation dating using archaeomagnetic directions and archaeointensities has been used for Neolithic and younger cultures. Directional dating can sometime

In recent decades, knowledge of past climate has been revolutionised by measurement of the oxygen isotope ratios of fossil microfauna in cores extracted from sediment on the floor of the dee
