Stable Isotopes in Archaeology

The application of the field of organic chemistry called stable isotope analysis has been used to identify evidence for human dietary elements like maritime creatures such as whales, fish and shellfish, various domesticated plants such as corn and millet, and cattle dairying and mother’s milk. Here are a few applications on this burgeoning topic.

Stable Isotopes: History of the Research
The very first archaeological application of stable isotope research was by South African archaeologist Nikolaas van der Merwe, who was excavating at the Iron Age site of Kgopolwe 3

Stable Isotopes in Archaeology: Applications
The application of stable isotope analysis to archaeological questions is about 30 years old; and since this innovative research was conducted in the mid 1970s, the variety and number of applications have exploded.

Natural Processes of Stable Isotopes
An explanation of the chemical reactions of stable isotopes; not for the faint of heart.

Stable Isotopes for Dummies
This essay is a vastly over-simplified discussion of why stable isotope research works. If you are a stable isotope researcher, the imprecision of the description will drive you mad; but it is a fairly accurate description of the natural processes used by stable isotope researchers today.

Stable Isotopes in Archaeology: C3, C4, and CAM Plants
An important part of understanding why stable isotopes can identify dietary inputs is because plants have different chemical makeup, called C4, C3, and CAM.

A selected list of references about archaeological applications of stable isotope research.

Bone Chemistry and Stable Isotopes
From Robert Tykot at the University of South Florida, an explanation of how stable isotopes are used to reconstruct prehistoric diets.

Overview of Stable Isotope Research
