What is stable isotope analysis?
Stable isotope analysis involves measuring the ratios of isotopes in materials to infer information about diet and environment.
Why is this method considered nondestructive?
The method preserves the integrity of the samples while allowing for analysis, making it suitable for valuable archaeological finds.
What types of questions can this method address?
It can answer questions related to diets of domesticated animals, management strategies, and animal mobility.
How can newcomers learn this method?
Visual demonstrations and detailed protocols are essential for effective learning and application of the method.
What materials are used in the sampling process?
The primary material used is tooth enamel carbonate from archaeological and paleontological samples.
Is there a risk of contamination during sampling?
Careful cleaning and handling procedures are designed to minimize contamination risks during the sampling process.
