Isobar’s Webinar: Migration Studies & Geographic Origin
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.
Lead Isotopes in Archaeology
In archaeological studies, lead isotopes are measured for two main applications: tracing origin of metal artefacts and reconstructing human origin and migratory patterns.
Analysing lake sediment cores: from dating to paleoclimate reconstructions
Sediments used for climate and environmental reconstructions come in many different forms (including lacustrine, marine, peat, terrestrial and aeolian deposits) and can be characterized by their grain size, shape, sedimentary facies, chemical and biological composition and accumulation/sedimentation rate.
Bones Webinar: Isotopes in Dating, Diets and Migration Studies
Isobar Science and Beta Analytic’s bones webinar focuses on C-14 and U-Th methods for bone samples. Topics include optimal sample types, common issues, and how to prepare bone samples for isotopic analysis.
Geochemistry: Stable and Radioactive Isotopes
In geochemical research, stable and unstable isotopes are used to understand the chemistry behind natural processes. Isotopes are different forms of a single element, with differing numbers of neutrons within their nucleus, resulting in different atomic masses.
Analysing Water Samples
Stable and radioactive isotopes can be analysed in groundwater and surface water samples in order to assess the magnitude and origin of pollution, rate of pollution infiltration into the environment, and timing of water interactions with the atmosphere.
Mineral Dust Samples: Analysing Strontium (Sr), Strontium-Neodymium-Hafnium (Sr-Nd-Hf) and Lead (Pb) Isotopes
The origin and movement of atmospheric dust can be estimated by analysing the geochemistry of dust collected directly from the atmosphere or from the dust layers found within ice cores or lacustrine and ocean sediment cores.
Isotopic analysis in forensic geography
Using isotopic analysis of skeletal remains and forensic evidence, one can reconstruct human profiles, analyse the environmental conditions antemortem and estimate the time of death. Other forensics-related investigations using isotope geochemistry include the analysis of trace evidence materials as well as provenancing illegal wildlife, bullets, narcotics, and other forensic evidence.
