Ice core records are an important foundational archive for paleoclimatology. Through them scientists have reconstructed high resolution atmospheric CO2 and temperature records covering hundreds of thousands of years.
Isobar Science is now offering a Strontium Chronology Service for dating marine carbonate samples. Strontium Isotope Ratios (87Sr/86Sr) within the ocean have varied through time, creating a predictable seawater curve that can be used for dating calibration.
Bones and teeth can be used for a variety of different isotopic analyses, including Oxygen, Strontium, Lead, Neodymium, Carbon, Nitrogen and dating (radiocarbon and in some cases Uranium-Thorium). There are important requirements for bone samples to ensure they produce accurate results.
Archaeological textiles can provide important evidence of social traditions and status, the economics of textile exchange, and evolving weaving technologies.
Isobar’s webinar will focus on boron and strontium to identify isotopic variability in the hydrosphere, including identification of pollution sources.
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.
Maps demonstrating variability in specific isotopes across a landscape have been produced in varying spatial resolutions (local, regional, global) – known as isoscapes.
In petroleum exploration, it is vital to be able to interpret and date key occurrences within petroleum systems – including petroleum generation and alteration (post-generation). For example, identifying and dating the occurrence of certain authigenic minerals (e.g. carbonate cements) can provide information on when and where oil is likely to accumulate to aid in targeting exploration.
