Quality Considerations for Bone Samples
Bones and teeth are relatively common within the archaeological and paleontological record due to the tendency for high preservation after burial.
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.
Discovering the source of Metal Artifacts using Lead Isotopes
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.
Cave Deposits: Chronology Development & Environmental Reconstruction
Caves are natural intact cavities found in many different landscapes which have been accessible to humans and animals for millions of years.
The Altitude Effect of Biogenic Apatite
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.
Archaeological investigations of caves
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.
Isotopes & Dating in Marine Environments
There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.
