AbstractThis research project concerns the study, analysis and dating of obsidian flows on the island of Lipari, in relation to the population of the Aeolian Islands, during the Neolithic period.The collection, processing and diffusion of Lipari obsidian characterise the Neolithic population of Lipari and the entire Mediterranean. By improving the knowledge of supply methods in the territory, it will be possible to formulate hypotheses on the chronology of the sources, the ways of collecting the raw material and on the mobility of the Neolithic communities in the Aeolian Islands. The scientific research is divided into two main topics: the first concerns the analytical and methodological aspects of archaeological and geological studies of Lipari obsidian; the second, the formation of obsidian at Lipari, their sources and lithological characteristics. Throughout the duration of this study we will perform new age determinations of Neolithic obsidian artefacts and geological samples, directly with the method of fission track, and indirectly dating paleo soils using the radiocarbon method.

Straits Of Messina

The Aeolian Islands are situated off the north coast of Sicily, not far from the entrance to the Straits of Messina. They can be reached by a daily service of steamboats from the port of Milazzo, 20 miles west of Messina. There is a daily train, called Freccia di Sul, that goes direct from Milan to Palermo, stopping at Milazzo; The northernmost of the islands is Stromboli with its famous active volcano. The chief town is Lipari on the island of that name; here on its acropolis excavations directed by Professor Bernabo Brea on behalf of the Soprintendenza alle Antichita della Sicilia Orientale have revealed a stratified succession of huts, ranging from the neolithic period down to Hellenistic, Roman and modern times. These excavations and others on other islands have shown that, small though they be, the islands once played an important part in the culture of the western Mediterranean.

AbstractWe present the preliminary results of the ongoing investigation of the obsidian from the Bronze Age village of San Vincenzo, Stromboli, Aeolian Islands, for the purpose of providing technological and typological characterization, and also provenance of the raw material, the latter with non-destructive p-XRF. Regarding provenance, the source of the raw material is likely to be neighbouring Lipari. It was transported to Stromboli and used mostly in a highly opportunistic manner and for the production of blade(let), non-bladelike tools (mainly scrapers) and micro bladelets. The obsidian distribution around the site shows concentration in both domestic and production areas.

SummaryPrevious radiometric age determinations for the Criffell–Dalbeattie and Cairnsmore of Fleet Newer Granite intrusions are briefly reviewed. Thirteen fission-track dating results are presented for the co-existing accessory minerals sphene, zircon and apatite separated from the two granites. The mean sphene apparent age of 401±10 Ma and single zircon apparent age of 389±26 Ma are interpreted as the age of initial post-intrusion cooling of the granites. Results from apatite are discordant with those of sphene and zircon. Four determinations give a mean Upper Cretaceous apparent age of ∼ 80 Ma which is not readily interpreted. A single apatite determination upon a sample located adjacent to a basaltic dyke yielded a Tertiary age.

The Vilapedre axe (Lugo, Northwest Iberia) has been traditionally considered by archaeologists as evidence of prehistoric long-distance contacts along the Atlantic Coast of France and Spain. This artefact - as other “Tumiac type” axes (long polished blades, generally butt-perforated) - would have been produced in Brittany during the Neolithic (5th millennium BCE) using jadeitite as raw material, a green-coloured rock for which there are sources in the western Italian Alps. In this paper, we have traced the possible archaeological origin of this artefact back by examining the personal files of one of its first owners, Santiago de la Iglesia. Furthermore, we have conducted a mineralogical (X-Ray Diffraction, XRD) and an elemental analysis (Scanning Electron Microscopy with Energy Dispersive X-ray Detection, SEM-EDX) of both the Vilapedre axe and geological samples from several places at the Alps where prehistoric quarrying of greenstones has been reported. The aims were physicochemically characterizing the axe to provide information about its possible geological source. During our analyses, we have found significant compositional similarities between the Vilapedre axe and one of the geological samples coming from the Alps (Alp06). The results are therefore consistent with the alleged Alpine origin of this artefact. The presence of this axe in Northwest Spain, together with other evidence, such as the presence of objects of Iberian origin in Breton monuments, strongly suggests the existence of contacts between both regions of the Atlantic façade during the Neolithic onwards in which seafaring would undoubtedly have played an important role.

Age Determinations

The Tertiary igneous activity in West Greenland has not been dated in detail. Sediments contemporaneous with, or slightly older than, the early volcanic rocks are assigned amiddle Paleocene age from palaeontological evidence (Henderson et al., 1981), and palaeomagnetic work by Athavale & Sharma (1975) indicates that the Vaigat Formation picrites and the lower 500 m or so of the overlying Maligât Formation (Hald & Pedersen, 1975) were erupted in the time span represented by geomagnetic anomaly 25 together with the long reversal period between anomalies 25 and 24. The age estimated for this period is 56 to 52 Ma (Butler & Coney, 1981). The late Stage lamprophyre magmatism on Ubekendt Ejland appears to be much younger, about 30 to 40 Ma (Parrott & Reynolds, 1975). No reliable radiometric age determinations have been published from the Disko-Nûgssuaq area.

Antibiotic Residue

Antibiotic residue in milk may have harmful consequences for humans and milk technology. In order to prevent adverse effects of residue, nowadays different screening methods are used for qualitative examination of antibiotic residue in milk. The aim of the work was to investigate the presence of antibiotic residue in the samples of milk from different phases of production chain (from raw material to final product) by using different screening methods. Three screening methods, that are most often used, were chosen. Microbiological inhibitory methods: Delvo SP test and diffusion method with B. stearothermophilus and enzyme method Penzyme S test. A total of 60 samples were examined. The samples were collected from whole milk production chain from farm to final product. The investigation determined high compatibility of tests. The differences that occur in examining the same sample using three different methods are a consequence of different sensitivity of the methods. Delvo SP test is sensitive to antibiotics, sulphonamides, disinfectants and inhibitory substances in milk (lactoferin, lactoperoxidase). Diffusion method is sensitive to antibiotics, while Penzyme S is sensitive only to β-lactam antibiotics. High coincidence of Penzyme S test with two other tests prove that β-lactam antibiotics are the most often residua that can be found in milk. The differences in results may also be a consequence of difference of detection limit for the same antibiotics. On the basis of performed investigation, it was detected that there is a high percent of milk sample that contain antibiotic residues 30% in bulk tanks on farms, 20% in cistern in diary and 20% in pasteurized and sterilized milk on the market. On the bases of parallel investigation of diffusion method, Delvo SP test and Penzyme S test, we can conclude that all three methods are extremely in agreement and thus they fulfill one of the criteria for introducing them in systematic milk control on presence of antibiotic residue.
