Methods dating artefacts
Radiocarbon analysis can only be used on organic materials, and is often used to date charcoal associated with campfires and archaeological deposits.
Potassium-argon (K-Ar) dating is a radiometric technique that is used to determine the age of minerals that contain potassium, which include clay minerals and micas.
To determine the year age (absolute age) of an object, a number of chemical and radioactive techniques can be used.
Four main methods have been used in Willandra archaeology.
'To prove my hypothesis I carried out a series of dives and discovered 50 anchors.
Working out how old archaeological remains are is a vital part of archaeology.
This well known method was the first technique that became available for accurate dating of old materials.
It uses the fact that natural carbon contains a known ratio of ordinary carbon and the radioactive isotope carbon-14, and that this mix is reflected in carbon taken up by living organic materials such as wood, shells and bones.
The technique is inherently holistic, drawing upon understanding from disciplines such as physics (quantum mechanics), mineralogy (grain structure and composition), geochemistry (natural radioactivity), archaeology and Earth sciences.
This issue brings together contributions on new and innovative luminescence dating methods and the latest findings related to Earth-surface processes and human existence.
