Another important subdiscipline of archaeometry is the study of artifacts.
Archaeometrists have used a variety of methods to analyze artifacts, either to determine more about their composition, or to determine their provenance.
These techniques include: Lead, strontium and oxygen isotope analysis can also test human remains to estimate the diets and even the birthplaces of a study's subjects.
Archaeometry is an important tool in finding potential dig sites.
The use of remote sensing has enabled archaeologists to identify many more archaeological sites than they could have otherwise.
The use of aerial photography (including satellite imagery remains the most widespread remote-sensing technique.Ground-based geophysical surveys often help to identify and map archaeological features within identified sites.Provenance analysis has the potential to determine the original source of the materials used, for example, to make a particular artifact.This can show how far the artifact has traveled and can indicate the existence of systems of exchange.Archaeometry has greatly influenced modern archaeology. Archaeologists can obtain significant additional data and information using these techniques, and archaeometry has the potential to revise the understanding of the past.For example, the "second radiocarbon revolution" significantly re-dated European prehistory in the 1960s, compared to the "first radiocarbon revolution" from 1949.
