Water: Dating & Isotopic Analyses
Water’s continuous movement and flow of water across landscapes contribute
to and provide important clues into the intricacies of biogeochemical cycles
at various spatial and temporal scales.

Limestone: Dating & Isotopic Analyses
Limestone is a granular sedimentary rock predominantly composed of
calcium carbonate (CaCO3), which commonly forms along shallow ocean
water beds from fossilized shells and exoskeletons of marine organisms.
Provenancing Dust in Ice Core records using Isotopes
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.
NEW Strontium Chronology Service Available
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.
Best Practices When Selecting Bone Samples
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.
Identifying Origin and Trade of Textiles using Strontium Isotopes
Archaeological textiles can provide important evidence of social traditions and status, the economics of textile exchange, and evolving weaving technologies.
Free Webinar on Strontium + Boron in Hydrochemistry
Isobar’s webinar will focus on boron and strontium to identify isotopic variability in the hydrosphere, including identification of pollution sources.
Free Webinar on Marine Environments
Isobar Science and Beta Analytic invite researchers interested in isotopes and dating to view this FREE webinar: Isotopes & Dating in Marine Enviornments
Isoscapes in Food Science
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.
Strontium & Neodymium Case Study: Connecting Atmospheric Dust to Source Region
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.
