Selected AbstractsPHOSPHATES IN ARCHAEOLOGICAL FINDS: IMPLICATIONS FOR ENVIRONMENTAL CONDITIONS OF BURIAL,ARCHAEOMETRY, Issue 4 2004L. MARITAN The occurrence of coarse-grained vivianite and mitridatite aggregates in a potsherd, a grand ring and a timber imprint from the Second Iron Age site of Adria (Rovigo, northeastern Italy) suggest contrasting environmental conditions of burial. In particular, bone fragments were replaced by vivianite at relatively low pH and Eh, due to the presence of deteriorating organic matter, together with slag and iron flakes. Subsequent interactions with Ca-rich groundwater characterized by higher pH and Eh determined the growth of mitridatite after vivianite. Although phosphates crystallized after burial, the examined samples were not involved in pervasive chemical contamination. [source] Evidence for Indo-Roman Trade from Bet Dwarka Waters, West Coast of IndiaINTERNATIONAL JOURNAL OF NAUTICAL ARCHAEOLOGY, Issue 1 2006A. S. Gaur India had a very active maritime trade contact with the Roman world between the 4th century BC and the 4th century AD. In this context recent finds of stone anchors, potsherds, lead anchors and a lead ingot from 5 to 8 m water-depth near Bet Dwarka jetty is significant. The sherds include amphoras, jars, bowls and lids. Archaeological finds along the Indian coast and comparison between amphoras from Bet Dwarka and the Mediterranean suggest that the artefacts from Bet Dwarka may be datable to between the 1st century BC and the 2nd century AD. The numbers of stone anchors suggests that this was an ancient anchorage. © 2005 The Nautical Archaeology Society [source] To be or not to be a cog: the Bremen Cog in perspectiveINTERNATIONAL JOURNAL OF NAUTICAL ARCHAEOLOGY, Issue 2 2000Ole Crumlin-Pedersen Following on from Thijs Maarleveld's paper in 1995 on type-names for archaeological finds of ships, the use of the term cog has been questioned by Timm Weski, who suggested the archaeological term Ijsselmeer-type instead. The present paper surveys a total of 18 ship-finds of this type with respect to date, origin and year of investigation, without finding support for the proposed change in terminology. Instead, the archaeological term cog should be restricted to seagoing vessels of the 12th,15th centuries which share the structural features of the lower part of hull with the Bremen Cog. Recent results of dendroanalysis point to the root of the Jutland peninsula as a more likely area than the former Zuiderzee for the transformation of a hypothetical older,proto-cog'-type for navigation on rivers and in the Waddensee into the proper seagoing medieval cog-type. Impulses for this transformation were found, most likely, in the need to circumnavigate Cape Skagen already in the 12th century, and technical features were probably taken over from large Scandinavian cargo ships of that period. © 2000 The Nautical Archaeology Society [source] GLAZED CERAMIC MANUFACTURING IN SOUTHERN TUSCANY (ITALY): EVIDENCE OF TECHNOLOGICAL CONTINUITY THROUGHOUT THE MEDIEVAL PERIOD (10TH,14TH CENTURIES),ARCHAEOMETRY, Issue 1 2008C. FORTINA Archaeometric investigation allowed the characterization of two important classes of ceramics: ,vetrina sparsa' and ,invetriata grezza'. Their archaeological peculiarity makes them particularly suited for tracing the evolution of glaze manufacturing in southern Tuscany throughout the medieval period (10th,14th centuries). These ceramics were found in different sites of historical importance, and also from a mining perspective. Local copper, lead, zinc and iron mineralizations supported the growth of several settlements in the vicinity of the mines. The many castles and different archaeological finds (ceramics, glazed ceramic, slag etc.) attest to the intense mineral exploitation of the area from at least the first millennium bc up to the modern period. In light of these geological and archaeological characteristics, archaeometric investigation was intended to provide insight into ancient technical knowledge of ceramic glazing and to determine the source area for raw materials in the medieval period (10th,14th centuries). Ceramic bodies were analysed through OM, XRDp, SEM,EDS and XRF, while coatings were investigated through SEM,EDS. Mineralogical, petrographic and chemical analyses revealed slightly different preparation and firing processes for the two classes of ceramics. These data suggest the continuity through the centuries of the ,vetrina sparsa' and ,invetriata grezza' production technology. The mineralogical phases, such as monazite, xenotime, zircon, barite, Ti oxide, ilmenite, titanite, tourmaline and ilvaite, and the lithic (intrusive and volcanic) fragments detected within the ceramic bodies suggest a source area in the vicinity of the Campiglia mining district. Lastly, the presence of Cu,Zn,Pb (Ag) and Fe sulphide mineralizations (materials used to produce glaze) in the area supports the hypothesis of local manufacture. [source] | ||||||||||
