楚史书《梼杌》的名源与三星堆青铜人头像性质考

《孟子·离娄下》所说楚国史书《梼杌》的名称来源是来自南方楚国先祖祭主的名称,古代把圆木柱称作"梼杌"并用来作为先祖祭主,后来便称记载先祖历史的史书也叫做"梼杌"。套在圆木桩上的三星堆青铜人头像与成都金沙木雕彩绘人头像的形制一样,本为南方古国的圆木桩形制的先祖"梼杌",其性质是用来祭祀先祖的祭主。"梼杌"是长江流域巴蜀楚地以断木做成的先祖祭主之状,而青铜立人像是木质先祖祭主的仿制品,青铜人头像用青铜做成再套在断木之上的先祖祭主。     

Changes in sub‐water table fluid flow at the end of the Proterozoic and its implications for gas pulsars and MVT lead–zinc deposits

A fundamental change in the nature of sub‐water table fluid flow occurred at roughly the Proterozoic–Phanerozoic boundary when organic matter began to be buried in sufficient quantities that nonaqueous fluids could occupy a significant fraction of the pore space. This allowed the formation of remarkably durable capillary seals that could trap gas in large portions (hundreds of kilometers) of a basin for hundreds of millions of years. Gas loss from these gas zones can be highly dynamic, especially during gas generation. Under the right circumstances, hundreds of cubic kilometers of gas can be rapidly discharged into adjacent permeable aquifers. In Pennsylvanian/Permian time, the Arkoma Basin may have repeatedly discharged such volumes of gas into the very permeable Cambrian sandstone and karstic carbonate aquifers of the mid‐continent of the United States. This could have displaced brines rapidly enough to form the Mississippi Valley‐type (MVT) lead–zinc deposits of this age that are associated with the Arkoma Basin, heating them only briefly as required by maturity indicators. Sea level rise accompanying the melting of Permian continental glaciers may have triggered the gas expulsion events. This radically new mechanism for the formation of MVT deposits is just one example of the nonlinear dynamics of gas accumulations that are possible since Late Proterozoic time.     

Of Ships and Deer: early Western Mediterranean ship graffiti reappraised

Re‐analysis of the Hal Tarxien prehistoric ship graffiti, the incised figure on a pottery sherd, from the Neolithic site of Grapceva cave on a Croatian island, known as the ‘Hvar boat’, and the Villanovian‐Etruscan bronze razor from Bologna allow the last two to be reinterpreted as animals rather than ships, and the first to be dated to the Bronze Age Cemetery phase of the site. These findings require the earliest ship graffiti in the western Mediterranean to be reconsidered.     

Seal dies from the National Museum of Slovenia: Non-destructive analyses of medieval and early modern copper alloys

A representative group of seal dies made of copper alloys from the collection of the National Museum of Slovenia was investigated by energy-dispersive X-ray fluorescence spectrometry (EDXRF). Chronologically, the artefacts date from the early 13th century to the present. Non-destructive EDXRF screening of elemental fingerprints of Cu, Zn, Pb, Ag, Sn and Sb was performed on 95 seal dies, and the obtained elemental data set was further processed by chemometric tools such as principal component analysis (PCA). The relationships between the elemental composition of analysed seal dies, type of alloy applied and their historical context—date, location of manufacture and, possibly, social rank of the owner—were examined in detail.     

两周金文中的繁地与西周早期的东土经略

两周金文中的繁与繁阳,是全然不同的两个地名:繁为东土地名,似在今山东汶、泗之间,繁阳则为南土汝水流域地名,在今河南新蔡一带。甗铭文所记周王命令出使于繁,班簋铭文记录穆王令毛公掌管繁、蜀、巢诸地,均与西周早期王朝东土经略有关。汶水流域是中原王朝东拓的交通要地,具有重要战略意义,也是今人梳理商周东土拓殖史的要点之所在。     

About two seal-impressed jars from Tell Abraq (Emirate of Umm al-Quwain). New evidence for intercultural networks in the lower Arabian Gulf in the late 2nd – beginning of the 1st millennium BC

Ongoing excavations at Tell Abraq (Emirate of Umm al-Quwain, U.A.E.) are revealing new aspects of this multiperiod site, which was occupied from c. 2500 BC to 300 AD. Together with substantial architecture dated to the 2nd and 1st millennia BC, relevant assemblages of archaeological materials are being collected and dated to different phases of the site’s life. Among this material, exceptional is the discovery of two jars bearing the impression of two different cylinder seals, which will be presented here. Seal impressions on any media are extremely rare in the whole of south-eastern Arabia and strongly indicate a foreign provenance for the jars. Their iconographic study, the fabric and morphological parallels for the jars, and probable chronology will be discussed, as this can highlight transmarine connections during the late 2nd-first half of the 1st millennium BC, as well as provide new data to address chronological issues in south-eastern Iran itself.     

The Question of "Why It Is in Henan" and the New Direction of Chinese Scientific and Technological Archaeology

The ritual institutionalization demonstrated in the bronze production at Erlitou and further developed during the Shang and Zhou periods that formed a distinctive feature of bronze civilizations. While exploring the path of the earliest state formation, we could consider why Erlitou was chosen from the unveiling of the Bronze Age in China. Much attention had been paid to archaeological, chronological, geographic, and climatic information in the existing studies, but the relationship between bronze metal resources and the formation of the Erlitou state needed more attention. Viewing the Erlitou culture as the earliest state form in China and thus exploring the path of formation of early states was a return to the original theme of archaeology.     

A Compositional and Microstructural Study of Eighth‐Century BC Bronzes from Moita Da Ladra (Tagus Estuary): How Did the Spread of the Phoenician Metallurgy Take Place in Western Iberia?

Metals from a votive deposit at Moita da Ladra (Tagus Estuary) dating to the eighth century bc were studied by micro‐EDXRF, optical microscopy and Vickers testing to investigate the adoption of Phoenician innovations by indigenous communities. Artefacts are made of bronze alloys with suitable tin contents (11.6 ± 2.3 wt%) and very low iron impurities (<0.05 wt%), and were often manufactured using the long post‐casting sequence. Comparisons with indigenous and Phoenician metallurgies from western Iberia revealed a conservative technology suggesting that the spread of Phoenician innovations was very slow. In this region, the adoption of a diversified copper‐based metallurgy and reduction furnaces only seems to occur during the Post‐Orientalizing Period, c. sixth to fourth centuries bc .
