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.
Please be informed the Miami lab will be closed on the following dates:
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.
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.
Biogenic apatite is a molecule made up of calcium, phosphorus and oxygen. Importantly, the phosphorus is found primarily in the form of phosphate (PO4) – which is present in both soft and hard tissues in organisms.
Caves – or rock shelters – have been studied by archaeologists for the past two centuries, with specific focus on the investigation of prehistoric cave paintings, ceremonial use and other evidence of occupation.
There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.
