This 'law of superimposition' works in the well-defined layers of the Willandra lunettes, but only dates objects as younger or older than adjacent layers.

To determine the year age (absolute age) of an object, a number of chemical and radioactive techniques can be used.

In the Willandra area it is typically used on quartz sand grains which have been buried and have not been exposed to sunlight since burial.

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.

Dates above and below a location provide minimum and maximum age determinations according to the law of superimposition.

Thermoluminescence is a similar technique to optical dating, but uses heat instead of light to stimulate the minerals.
