Biogenic apatite is a molecule made up of calcium, phosphorus and oxygen. Importantly, the phosphorus is found primarily in the form of phosphate (PO4) – which is present in both soft and hard tissues in organisms.
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.
The concentration, composition and circulation of atmospheric dust can play an important role in the global radiation budget. Sr-Nd-Hf isotopes are inherent in many geological settings and have been used to track the origin of sediments and dust.
Maps demonstrating variability in specific isotopes across a landscape have been produced in varying spatial resolutions (local, regional, global) – known as isoscapes.
The details of animal origin and migratory routes through terrestrial and aquatic systems can be traced through the analysis of various stable isotopes including strontium, neodymium, carbon and oxygen.
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.
