Mercury levels in sediments of central Mediterranean Sea: a 150+ year record from box-cores recovered in the Strait of Sicily.
2006
To evaluate the degree of anthropogenic mercury pollution, Hg contents have been measured for box-core sediments sampled along three nearshore-offshore transects in the Strait of Sicily and well constrained for their mineralogy, bulk geochemistry and TOC%. Hg values are generally low (from 15 to 70 microg kg(-1)); however, depth profiles clearly display upcore rising concentrations (up to 202 microg kg(-1) near the SE Sicily coast) that are attributed to anthropogenic load. Based on (210)Pb chronology, these trends are more dramatic across the last 20-30 years. Geogenic influence is thought to explain some anomalies related to volcanic emission and geothermal activity. Combined effects due …

La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia
2021
Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…
Towards a dendrochronologically refined date of the Laacher See eruption around 13,000 years ago
2020
Highlights • Previous age estimates of the Laacher See Eruptions (LSE) around 12,900 years are still diverging and imprecise. • The combination of dendrochronology, wood anatomy, and 14C measurements holds the potential to establish a precise LSE date. • An absolute calendric date of the LSE would improve the synchronization of European Late Glacial to Holocene archives. Abstract The precise date of the Laacher See eruption (LSE), central Europe’s largest Late Pleistocene volcanic event that occurred around 13,000 years ago, is still unknown. Here, we outline the potential of combined high-resolution dendrochronological, wood anatomical and radiocarbon (14C) measurements, to refine the age …
Multianalytical characterization of pigments from funerary artefacts belongs to the Chupicuaro Culture (Western Mexico): Oldest Maya blue and cinnaba…
2019
Abstract The colours used in Pre-Hispanic Mesoamerica to decorate walls, codices or artefacts have been the subject of numerous studies, with particular attention to Maya blue, red and white pigments. However, most of these studies have been focused on emblematic cultures of the Classic period (ca. 300–1000 CE), such as Teotihuacan and Maya cultures. This work proposes a new chronology of the preparation and use of these pigments, particularly Maya blue, by analysing samples of the Pre-Classic period (ca. 1800 BCE–300 CE). The samples belong to ceremonial artefacts decorated with blue, red and white pigments, in a funerary context from the Chupicuaro culture, which was developed between 600…
Les sépultures de Truchtersheim "Holderacker" (Bas-Rhin) et les pratiques funéraires du Bronze A1 dans le sud de la plaine du Rhin supérieur
2023
Die Freilegung 2019 eines kleinen frühbronzezeitlichen (2030-1900 v. Chr.) Bestattungsensemblesin Truchtersheim „Holderacker“, etwa 12 km nordwestlich von Straßburg, hat uns bewegt uns mit der gesamten für das Elsassverfügbaren Dokumentation der frühbronzezeitlichen Bestattungssitten zu befassen. Dieser bisher kaum dokumentiertechronologische Horizont wurde kürzlich durch eine Reihe von Funden bereichert, die vorwiegend zwischen 2017 und 2019bei präventivarchäologischen Operationen im Vorfeld der Bauarbeiten der Westumgehung von Straßburg entdeckt wurden.Das bescheidene regionale Corpus mit 20 Gräbern erlaubt nur begrenzte Beobachtungen, es weist jedoch doch mehrere für dieFrühbronzezeit ch…
Late Pleistocene vertebrate - bearing deposits at San Teodoro Cave (North-Eastern Sicily): Preliminary data on faunal diversification and chronology
2008
Abstract This paper deals with the chronology and the possible correlations among levels of different excavated areas in the Pleistocene vertebrate-bearing deposits at the large San Teodoro Cave (North-Eastern Sicily). Two trenches have been excavated along the eastern side of the cave, located at a distance from the entrance, respectively, of 8 m ( α trench) and 28 m ( β trench) and at different depths. Lithological features, biometrical data from small mammals and ecological data from molluscs point to similar environmental conditions for the α trench deposits and those located along the eastern wall of the cave in the eastern part of the β trench. The same evidence, and the taphonomic fe…
Indirect chronology method employing rare earth elements to identify Sagunto Castle mortar construction periods
2017
A novel indirect chronology method has been developed to identify Sagunto Castle construction periods. The method is based on the use of inductively coupled plasma mass spectrometry (ICP-MS) to determine rare earth elements (REE) and other trace elements in mortars. Additionally, a no destructive geochemical analysis based on X-ray fluorescence (XRF) was employed for major elements determination. Collected chemical data were processed through Principal Component Analysis (PCA) to highlight any differences among the mortars belonging to different buildings and construction periods. The results show that PCA analysis permits to discriminate construction periods according to mortar sample REE …
