What's in a bone? Recent advances in archaeological bone chemistry

This paper focuses on advances in archaeological bone chemistry since 1989. At that time studies generally shifted from development and application of techniques in bone chemistry to more experimental approaches. In stable isotope studies, controlled feeding experiments have been carried out to determine the routing of various dietary components into bone tissues. Biological apatite has been added to collagen as a tissue of study for stable carbon isotope analysis, providing the ability to study much older remains. Other elements have been added such as hydrogen for the study of paleoclimate and oxygen and strontium isotopes to study life history. Trace element studies have focused on methods of detecting and controlling for diagenesis, and barium has been added to the list of useful dietary indicators. Attempts to extract DNA from archaeological bone have been successful, however, this field is still in its early stages in terms of applications to understanding prehistoric biological relationships.     

Painted birds at Pompeii

The wall-paintings in the houses at Pompeii and in other Campanian towns can provide evidence for the birds that were known in Italy in the first centuries BC and AD , because they are painted with remarkable accuracy. However, the paintings as total works of art must not be interpreted in too realistic a manner because the flora and fauna are often combined in an ideal setting. © 1997 John Wiley & Sons, Ltd.     

Ancient hydrocarbon seeps from the Mesozoic convergent margin of California: carbonate geochemistry, fluids and palaeoenvironments

More than a dozen hydrocarbon seep‐carbonate occurrences in late Jurassic to late Cretaceous forearc and accretionary prism strata, western California, accumulated in turbidite/fault‐hosted or serpentine diapir‐related settings. Three sites, Paskenta, Cold Fork of Cottonwood Creek and Wilbur Springs, were analyzed for their petrographic, geochemical and palaeoecological attributes, and each showed a three‐stage development that recorded the evolution of fluids through reducing–oxidizing–reducing conditions. The first stage constituted diffusive, reduced fluid seepage (CH₄, H₂S) through seafloor sediments, as indicated by Fe‐rich detrital micrite, corroded surfaces encrusted with framboidal pyrite, anhedral yellow calcite and negative cement stable isotopic signatures (δ¹³C as low as ?35.5‰ PDB; δ¹⁸O as low as ?10.8‰ PDB). Mega‐invertebrates, adapted to reduced conditions and/or bacterial chemosymbiosis, colonized the sites during this earliest period of fluid seepage. A second, early stage of centralized venting at the seafloor followed, which was coincident with hydrocarbon migration, as evidenced by nonluminescent fibrous cements with δ¹³C values as low as ?43.7‰ PDB, elevated δ¹⁸O (up to +2.3‰ PDB), petroleum inclusions, marine borings and lack of pyrite. Throughout these early phases of hydrocarbon seepage, microbial sediments were preserved as layered and clotted, nondetrital micrites. A final late‐stage of development marked a return to reducing conditions during burial diagenesis, as implied by pore‐associated Mn‐rich cement phases with bright cathodoluminescent patterns, and negative δ¹⁸O signatures (as low as ?14‰ PDB). These recurring patterns among sites highlight similarities in the hydrogeological evolution of the Mesozoic convergent margin of California, which influenced local geochemical conditions and organism responses. A comparison of stable carbon and oxygen isotopic data for 33 globally distributed seep‐carbonates, ranging in age from Devonian to Recent, delineated three groupings that reflect variable fluid input, different tectono‐sedimentary regimes and time–temperature‐dependent burial diagenesis.     

Bone chemistry and paleodiet

Bone chemistry paleodietary studies are emerging as important research areas in archaeology, biological anthropology, and paleontology. With appropriate controls, the inorganic and organic chemical composition of bones and teeth can provide information about past diet and habitat use. Chemical signatures are used to address individual dietary variability in early hominid fossils, paleontological remains, and more recent human and faunal populations.     

Archaeometric analysis of the ‘greco scritto’ marble slabs from the Edificio dei Triclinii at Murecine (Pompeii,Italy)

This paper presents the results of the archaeometric analysis of the greco scritto marble slabs from the Edificio dei Triclinii, an inn or statio negotiatorum discovered at Murecine in Pompeii’s suburbs in 1999–2000. A total of 14 samples were collected and subjected to standard X-ray diffraction (XRD), optical microscopy (OM) on thin sections and stable isotope ratio analysis (SIRA) to assess the stone’s identity and provenance. The results of this study substantiate the hypothesis (already put forward and based on a macroscopic identification by Perna and Scognamiglio) that the stone originates from the Hasançavuşlar quarries near Ephesus in Asia Minor, and represent the first step towards a systematic contextual and geochemical study of Ephesian greco scritto in Roman contexts and its respective contribution to the Roman stone trade.     

Archaeology and roman society: Integrating textual and archaeological data

Although the collection of new data and the development of an enduring interest in theoretical concerns characterize much current work in Roman archaeology, the field continues to experience, tension between traditional classical archaeological approaches and practices borrowed from other branches of archaeology. This tension is most clearly visible with the integration of textual and archaeological data. How the dynamic between these provenances plays out in Roman archaeology can be seen in theoretical and methodological applications, the use of field survey, and the adoption of an Annaliste perspective by some Roman archaeologists. Text and archaeology are crucial contributors to the the study of early Rome and its origins, investigations in the capital for all periods, the study of Pompeii, and attempts to illuminate the chief characteristics of the Roman economy. Many advances in Roman archaeology have occurred largely as a result of a conscious attempt on the part of Roman archaeologists to properly contextualize textual data in light of the archaeological data, thereby providing a better balance between the two sets of information and liberating archeeology from being the “handmaid of history.”     

Fluid systems and mineralization in the north German and Polish basin

The North European Basin hosts mineral deposits like the Kupferschiefer and the Mississippi Valley Type deposits in the Silesian sub‐basin in Poland. The basement to this basin, exposed in the Harz Mts and in the Flechtingen and Calvörde Blocks, contains Mesozoic Pb–Zn vein mineralization and barite–fluorite deposits as well as massive hematite veins in the Rotliegend volcanics. A comparison of the mineralizing models of these deposits with results from a basin‐wide petrographic, fluid inclusion and stable isotope study shows that the genesis of the mineral deposits can be explained by fluid systems that were active during different stages of basin evolution. These comprise syn‐ to post‐magmatic fluids derived from or mobilized in the course of the Rotliegend magmatism, fluids convecting in the Rotliegend units during the extensional basin subsidence in the Permo‐Triassic and originating from progressive devolatilization of the basin sequence and fluids derived from the overlying Zechstein evaporites. Deep‐reaching fault systems developing during the Cretaceous tectonic reactivation enhanced fluid percolation from the surface to the deep sections of the basin sequence. Identification and correlation of these fluids across the basin and in the mineralizations provide the base for a basin‐wide metallogenetic model.     

从嫁妆制度的变化看古罗马社会妇女的经济地位

古罗马实行的是嫁妆婚姻."女儿出嫁给予嫁妆"从一种习俗变成法律的硬性规定;嫁妆的数额经历了由少到多的变化;妻子对嫁妆的权利则经历着从无到有的演变.这是一个逐渐对妇女有利的发展过程,也是罗马财产让渡的一个发展过程,它对于妇女而言不仅仅是获取陪嫁物,更重要的是通过嫁妆参与了社会财产的分配.罗马妇女通过嫁妆制度参与社会财产分配与让渡,在罗马社会发展进程中起到重要作用,从而显示出自己独特的经济地位.     

Discovery of Ancient Harbour Structures in Calabria, Italy, and Implications for the Interpretation of Nearby Sites

During underwater survey around Crotone, Calabria, Italy, in 2005, structures from two harbour phases were located, possibly dating from the Archaic Greek and Roman periods. Both harbours are close to the Greek and Roman architectural remains on Capo Colonna, as well as to underwater deposits of large stone blocks and other, previously-excavated sites. With the discovery of these harbour structures, new hypotheses arise for understanding the building-material deposits and excavated sites. A critical component of these hypotheses is the assessment of local geological data, specifically ancient sea-level, in relation to the archaeological record.
