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.
There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.
Isobar Science and Beta Analytic invite researchers interested in isotopes and dating to view this FREE webinar: Isotopes & Dating in Marine Enviornments
Live Webinar: September 20, 2022 – 11:00 AM Eastern Time (US and Canada)
Speaker: Maren Pauly, PhD
Isobar Science offers Biogenic Apatite (CaPO4) analysis on bones and teeth samples.
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.
Uranium-Thorium (U-Th) dating is a radioactive method to date a variety of carbonate samples, including corals, cave deposits, cave artwork, shells, foraminifera and bone.
Maps demonstrating variability in specific isotopes across a landscape have been produced in varying spatial resolutions (local, regional, global) – known as isoscapes.
View our on-demand webinar on Isotope Applications: Bone Samples in Archaeology. Topics include when to use radiocarbon dating versus uranium-thorium dating.
