Carbon dating of wood
A number of methods are used, all of which have their advantages, limitations and level of accuracy.Complex dating problems often use a variety of techniques and information to arrive at the best answer.
It is most useful for minerals older than 100,000 years and can reach way back into the geological past.This technique can determine ages between a few hundred years to more than 100,000 years.It has been used at Willandra to date the layers above and below the location of Mungo Lady and Mungo Man , and the layers above and below the footprints horizon.Chemists conceive of these distances as shells, and define the properties of atoms by what is in each shell, according to the University of California, Davis.Carbon has two electron shells, with the first holding two electrons and the second holding four out of a possible eight spaces.

Carbon-14 has a half-life of 5,730 years so dating is limited to between a few hundred and about 50,000 years. It is also important that samples for dating are collected carefully to ensure they have not been contaminated with more recent carbon.
