Lead (Pb) has four stable isotopes (204Pb, 206Pb, 207Pb and 208Pb) which are commonly used in archaeological studies, particularly in the case of connecting metal artifacts to their relevant geological or mine sources.

Caves – or rock shelters – have been studied by archaeologists for the past two centuries, with specific focus on the investigation of prehistoric cave paintings, ceremonial use and other evidence of occupation.

Lead is a naturally occurring element found within the earth’s crust as well as in bodies of water, soil and overlaying plants. The rise and fall of lead use through space and time makes the reconstruction of lead isotopes very interesting for research into past civilizations and present environmental studies.
In the food industry, certain products and ingredients are more highly valued when they originate from specific regions of the world. Given the importance of designating an origin to products, geochemical fingerprinting can be used to identify product origin.
In petroleum exploration, it is vital to be able to interpret and date key occurrences within petroleum systems – including petroleum generation and alteration (post-generation). For example, identifying and dating the occurrence of certain authigenic minerals (e.g. carbonate cements) can provide information on when and where oil is likely to accumulate to aid in targeting exploration.
Lead isotopes (Pb) are known to be a very toxic non-essential element, with origins within the earth’s crust. Through anthropogenic activities, lead becomes altered and released into the atmosphere, where it acts as a trace aerosol pollutant.
Bones: Isotopes in Dating, Diets and Migration Studies
Live Webinar: April 14, 2022 – 2:00 PM to 3:30 PM Eastern Time
Isobar’s webinar on migration studies and geographic origin will focus on lead isotopes for tracking origin and trade of metal artifacts in addition to using strontium isotopes to track diet.
In archaeological studies, lead isotopes are measured for two main applications: tracing origin of metal artefacts and reconstructing human origin and migratory patterns.
