THE TUNGSTEN AND TIN SIGNATURE OF IRON ORES FROM ELBA ISLAND (ITALY): A TOOL FOR PROVENANCE STUDIES OF IRON PRODUCTION IN THE MEDITERRANEAN REGION

The mineralogy, petrography and major‐ and trace‐element composition of iron ores from Elba Island (Tuscany, Italy), one of the most important iron sources in the Mediterranean area since the first millennium bc , revealed that hematite‐rich ores display prominent enrichments in W and Sn (up to 4950 μg g^?1 and 8400 μg g^?1, respectively). These two elements are hosted by tiny grains of W–Sn mineral phases (ferberite, scheelite and cassiterite) that are disseminated throughout the hematite matrix. A comparison with iron ores from many Italian and European localities (most of which were exploited in ancient times) suggests the uniqueness of the geochemical pattern of Elba Island hematite‐rich ores (i.e., high W and Sn, low Mo and low Cu, Pb and Zn). We suggest that this geochemical signature may represent a new provenance marker not only for discarded ore at smelting/smithing sites, but, possibly, also for metallurgical slag and smelted metal produced in the chaîne opératoire of the iron process.     

THE GEOCHEMISTRY OF THE MAJOR SOURCES OF ARCHAEOLOGICAL OBSIDIAN ON HOKKAIDO ISLAND (JAPAN): SHIRATAKI AND OKETO

The geochemical compositions for obsidian from two of the most important sources on the Japanese island of Hokkaido, Shirataki and Oketo, are presented. This work represents the first systematic study of obsidian geochemistry on Hokkaido from the view of modern methodological standards. The study was performed with the help of neutron activation analysis to determine the concentrations for 28 elements. The results obtained allow us to subdivide both sources into two geochemical groups (Shirataki‐A and ‐B; and Oketo‐A and ‐B), with each representing an individual sub‐source. Obsidian from both Shirataki and Oketo sources is identified at archaeological sites located on Hokkaido, on the neighbouring Sakhalin Island and Kurile Islands, and in the lower course of the Amur River basin. The distance of obsidian transport during the Upper Palaeolithic was up to ～250 km, and in the following Neolithic and Palaeometal periods up to ～1200 km. This testifies to the wide distribution of Hokkaido obsidian to archaeological complexes in North‐East Asia and its active transport/exchange in prehistory. The data presented here should be used as a reference for the obsidian geochemistry of Shirataki and Oketo sources from now on.     

High Desert Paleolithic Survey at Abydos,Egypt

Abstract

In the winters of 2000 and 2002–2003 we surveyed a portion of the high desert immediately adjacent to the Nile Valley at Abydos, Egypt. The initial field season assessed the area's potential to contribute to the existing database of Paleolithic landscapes. Limited work done prior to our initial survey indicated that such Paleolithic sites in this region, while present, were relatively infrequent. Contrary to this expectation, we found the desert landscape densely littered with Paleolithic artifacts. Our subsequent work documented the extent of the distribution and the nature of Paleolithic artifacts. The goal of this work is to develop models of desert landscape use, particularly during the Middle Paleolithic, which can be integrated into those existing for the Nile Valley. In doing this, we provide a more complete picture of hominid adaptations in a place and time period critical to our understanding of the origins of modern human behaviors.     

'Going Local in a Global World': Locating the Public and Evaluating the Synchronic Context in Archaeological Resource Management

Abstract

Locating, and effectively engaging with, the public is part of the discussions that have taken place in the last two decades of archaeological resource management, within the context of changing post-colonial, 'ethically correct', democratic and indigenous-orientated perceptions. This article briefly reviews this wide area of thinking, examining an alternative methodology for locating and engaging with the public based on the notion of 'local', before presenting some results from the island communities of the Aegean.     

THE SEARCH FOR THE ORIGIN OF BITUMEN EXCAVATED FROM ARCHAEOLOGICAL SITES IN THE NORTHERNMOST ISLAND IN JAPAN BY MEANS OF STATISTICAL ANALYSIS OF FI–MS DATA*

The origin of bitumen excavated from archaeological sites in Hokkaido, the northernmost island in Japan, was sought by means of field‐ionization mass spectrometry (FI–MS) and gas chromatography – mass spectrometry (GC–MS) of the hydrocarbon components. The field‐ionization mass spectra were decomposed by Z‐numbers into several components, where the Z‐number refers to z in the formula C _n H _2n+z . This is equivalent to the deficit number of H atoms, when compared to the corresponding saturated hydrocarbon, which is related to the number of saturated hydrocarbon rings in alkanes. By use of the spectral intensities of the seven alkane components in each sample, multiple discriminant analysis was employed for the data of raw bitumen samples and excavated samples from archaeological sites. Based on this method and the gas chromatogram type, the following bitumen trade in the prehistoric age of Japan was elucidated: bitumen from Niigata, one of the main sources on the main island of Japan, spread to the north in 2000 bc , probably via the coastal zone, and reached a small island near the north end of Hokkaido. Bitumen from Sakhalin reached the central lowland in Hokkaido, but it went no further. Bitumen from Akita, another main source on the main island, spread over northern Honshu much earlier and reached the Oshima peninsula, the southwestern part of Hokkaido. The Akita bitumen scattered into the central lowland after the Niigata and Sakhalin bitumen. This area is believed to be the place where people from the south and the north met in those periods.
