Anthropogenic calcite is a form of calcium carbonate produced through pyrotechnological
activities, and it is the main component of materials such as lime binders and wood ash. This …

Electron spin resonance coupled with uranium-series dating (ESR/U-series) of carbonate
hydroxyapatite in tooth enamel is the main technique used to obtain age determinations …

Pleistocene climate variability is often seen as a major cause of much of the evidence
observed in the archaeological and palaeontological record of Africa. While continent-wide …

Lovedale is the only open-air Middle Stone Age site in the Free State dated to early Marine
Isotope Stage 4. Framing the chronology of this context, especially by taking into account …

In this study, we attempt to illustrate fossil vertebrate dental tissue geochemistry and, by
inference, its extent of diagenetic alteration, using quantitative, semi-quantitative and optical …

The Modder River basin has been the focus of extensive surveys followed by targeted
excavations of specific erosional gullies (known locally as dongas), where Middle and Later …

In this experimental work, the EPR signal intensity of hydroxyapatite (HAP) samples were
studied from a dosimetric standpoint. HAP samples have been prepared in a variety of ways …

In this study, electron beam dosimetry was performed by measuring free radicals induced in
synthesized hydroxyapatite using the EPR method. At first, synthetic hydroxyapatite (HAP) …
