The emphasis on tooth enamel for extraction of stable light isotope signals from the mineral phase of archaeological and paleontological calcified tissues is based on the widespread understanding that enamel remains a relatively closed system, while bone does not. Twenty years ago, however, Sullivan and Krueger s groundbreaking study demonstrating the potential of stable carbon isotopes from th...

Strontium (Sr)-isotope values on bone from deer mice pairs from 12 field sites in the Chaco Canyon area, New Mexico, were compared with isotope values of synthetic soil waters from the same fields. The data indicate that mice obtain Sr from near-surface sources and that soil samples collected at depths ranging from 25 to 95 cm contain Sr that is more accessible to the deep roots of maize; thus,...

BACKGROUND Paleoparasitology reveals the status of parasitic infections in humans and animals in ancient times based on parasitic particles found in biological remains from archaeological excavations. This line of research emerged in Iran in 2013. OBJECTIVE The identification of parasites from Neolithic times is an attractive subject that shows the oldest origins of parasitic infections in a ...

during archaeological survey in 2003, a unique pedestal has been found in a farm in owjtapeh (bukān) which, upon its artistic features, seemed to belong to iron age iii and to the site of qalaychi. this pedestal has been transferred to its present place after illegal excavations. there cannot be found a similar pedestal in iran, but there are some comparable samples in assyrian sites and inscri...

Analytical techniques play a fundamental role in heritage science. Among them, Particle Induced X-ray Emission (PIXE) and Fluorescence (XRF) are widely used many laboratories for elemental composition analysis. Although they well-established, strong effort is put on their upgrade, making them suitable more applications. Over the years, at INFN-LABEC (the laboratory of nuclear environment cultur...

Ancient potteries found at Ban Muang Bua, located in northeastern Thailand, associate with Thung Kula Ronghai culture. Most of them are products used daily life and grave goods. The potsherds were examined using techniques based on X-ray spectroscopy. Elemental composition morphology analyzed proton-induced emission spectroscopy (PIXE) scanning electron microscopy coupled energy-dispersive (SEM...

Sites containing Acheulian, Sangoan, Fauresmith, and Middle Stone Age artefacts occur within and below the Bedded Tuff, a widespread volcaniclastic member of the Kapthurin Formation, Kenya. The Bedded Tuff eruptive complex consists of up to twelve tephra beds, intercalated sediments, and paleosols. Two pumiceous units, high in the Bedded Tuff sequence, have been dated by(40)Ar/(39)Ar, one to 23...
