There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.
- Company Updates
- Sr Isotopes
- U-Th Dating
- Lead Isotopes
- Boron Isotopes
- Sr-Nd-Hf Isotopes
Isobar Science and Beta Analytic invite researchers interested in isotopes and dating to view this FREE webinar: Isotopes & Dating in Marine Enviornments
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.
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.
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.
Volcanic eruptions are significant geological events with far reaching implications. The analysis of isotopes in various sample types can provide information on the timing and magnitude of past volcanic eruptions.
Isobar Science and Beta Analytic’s webinar on sediments focuses on dating & environmental reconstructions. This complimentary webinar takes place on December 2, 2021 at 12:00 PM Eastern Time (US and Canada).
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.
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.
View our on-demand webinar “Geochemical Fingerprinting: Application of Sr-Nd-Hf-Pb Isotope Systematics in Earth Science.” Topics include: how different processes control the distribution of elements in the earth system; measuring Sr, Nd, Hf, and Pb and reporting conventions; application of Sr-Nd-Hf-Pb systematics in studying the governing processes in the earth system; research design and sampling strategies; and what to expect from your lab when measuring Sr-Nd-Hf-Pb isotopes.
