“…90 With the purpose of collecting both XRD and XRF data on the same spot of an object, a portable XRD/XRF 91 instrument was developed. Another technique which was used for limestone, 92,93 but also for pottery [94][95][96] provenancing was Instrumental Neutron Activation Analysis (INAA). Meyers and Vanzelts used INAA in their pilotstudy 97 to distinguish between objects made of limestone from different sources.…”
With the aim of identifying the origin and the manufacturer of a cement, a reliable procedure that provides unambiguous results is needed. Such procedure could resolve practical issues in damage...

“…A identificação e quantificação das concentrações elementares são realizadas por meio da espectroscopia gama, que utiliza a intensidade da radiação emitida pelo elemento instável para determinar os componentes e suas concentrações (Glascock et. al., 2004;Hancock e Carter, 2010;Thorn e Glascock, 2010;Tandoh et. al., 2010).…”

A arqueometria é uma área consolidada, com ampla utilização de métodos analíticos nucleares destrutivos e não destrutivos para caracterização, proteção e restauração de peças arqueológicas. O presente projeto teve como objetivo estudar a composição química elementar de amostras de fragmentos cerâmicos encontradas no sítio arqueológico São Paulo II localizado na calha do rio Solimões, próximo ao município de Coari na Amazônia Brasileira. Realizou-se a caracterização das amostras pela
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
