Four main methods have been used in Willandra archaeology.
This well known method was the first technique that became available for accurate dating of old materials.
In this article we shall discuss how we can use the paleomagnetism in rocks to attach dates to them (paleomagnetic dating).
The reader may find it useful to go back and read the main article on paleomagnetism before continuing.
The oldest and most widely used dating method in archaeology is typological dating.
An artefact is dated on the basis of knowledge about the age of other similar artefacts.
The amount of uranium present can be determined by irradiation to produce thermal fission of .
These ions are accelerated in an electric field through collimating slits and subject to a magnetic field which causes the ions to follow a curved path. By adjustment of the strength of the magnetic field and suitable placement of an ion collector, the different isotopes can be measured with precision.
There are some things that affect these measurements.
Thus, the ratio of naturally produced, spontaneous fission tracks to neutron-induced fission tracks is a measure of the age of the sample.
A wide variety of minerals have been fission-track dated, as have natural and artificial glasses.
