What is U-Th dating?

U-Th dating is an analytical method used to date calcium carbonate (CaCO3) bearing samples, including cave deposits/speleothems, CaCO3 rock, corals, shells and (in some cases) bones.

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

Register for our webinar on 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.

Isobar Science 2021 Holiday Schedule

Please be informed the Miami lab will be closed on the following dates: July 5, September 6, November 11, November 25-26, and December 23-January 2.

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.

Studying past climates using stable isotopes

The study of past climates (paleoclimatology) offers an opportunity to improve the predictability of future climate change. The stable isotopes of boron (δ11B) and oxygen (δ18O) are two important variables used to reconstruct climate in a variety of natural archives.

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.

Tracing the diet of herbivores and omnivores through isotopic analysis

Understanding the movement of herbivores across a landscape and ecological dynamics through time is important for current conservation and ecosystem management, while providing valuable insights into evolution and adaptation. Documented historical evidence in the relationship between organisms and their surrounding vegetation is generally limited and thus isotopic analysis of fossils can provide valuable insights into this important area of research.

U-Th Dating vs Radiocarbon Dating

The analysis of the uranium-thorium (U-Th) decay chain can be used to date a variety of calcium carbonate (CaCO3) bearing samples, including cave deposits (e.g. speleothems), calcium carbonate rock, corals, shells and (in some cases) bones. This method can be used to date samples existing from present day until 500,000 calendar years before present.
