Strontium dating (as enabled by the 87Sr/86Sr ratio of marine carbonates) can be used to date various marine samples based on the premise that the mixing of oceanic strontium occurs relatively rapidly through time compared to the residence time of oceanic strontium.
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.
Archaeological pottery samples can be provenanced through the analysis of the origin of its component clay and temper.
Bones and teeth are relatively common within the archaeological and paleontological record due to the tendency for high preservation after burial.
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.
Lead (Pb) has four stable isotopes (204Pb, 206Pb, 207Pb and 208Pb) which are commonly used in archaeological studies, particularly in the case of connecting metal artifacts to their relevant geological or mine sources.
Caves are natural intact cavities found in many different landscapes which have been accessible to humans and animals for millions of years.
