Sr-Nd-Hf Isotopes

Sediments Webinar: Dating & Environmental Reconstructions

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).

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.

Mineral Dust Samples: Analysing Strontium (Sr), Strontium-Neodymium-Hafnium (Sr-Nd-Hf) and Lead (Pb)

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.

Isobar’s Webinar: Application of Sr-Nd-Hf-Pb Isotope Systematics in Earth Science

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.

Strontium, Neodymium, Hafnium, and Lead Isotope Systematics in Earth Science

Sr, Nd, Hf and Pb are four isotopes that are inherent in many geological settings, and thus have been used to trace the evolution of metamorphic and igneous rocks, track the origin of sediments and dust, analyze weathering regimes and reconstruct past ocean circulation.

Sr-Nd Isotopes for Weathering Studies

Continental weathering is an important part of the global carbon cycle. The measurements of strontium and neodymium isotopes have been especially important in this research domain.
