Carbonates, Speleothem Archaeological (U-Series)
Archaeological carbonate speleothems: Deposits of secondary carbonate minerals (usually calcite or aragonite consisting of CaCO3) that formed in caves containing artefacts or other evidence of past human or hominid occupation
U-series dating such as U-Th (or 230Th/U) is a well-established, accurate, and precise method with a wide range of applications in earth sciences, palaeoclimate research, and archaeology (Bourdon et al. 2003). U-series dating can be used to determine the age of materials that formed with a well-constrained radioactive disequilibrium between U and its daughter isotopes, including precipitates of calcium carbonate (CaCO3) in cave environments, i.e., speleothems like stalagmites, stalactites, or flowstones. U-series dating is essential for palaeoclimate research using speleothems but is less commonly used for archaeological applications. However, cave environments are often associated with archaeology and archaeological finds. Excavations in...
