咸阳龚西战国秦墓出土铜壶制作工艺研究

咸阳龚西战国秦墓出土的青铜器为研究战国时期秦青铜容器的铸造技术提供了重要实物资料。本文对龚西战国晚期秦墓M8出土的两件铜壶,通过表面观察结合X光摄像考察其制作工艺痕迹,利用金相显微镜、扫描电镜能谱分析等手段开展成分及显微结构分析,揭示两件铜壶壶身及表面装饰的制作工艺、材质特征。结果显示,两件铜壶均为铸造,器底和铜环预先铸好后置于范中,与器身铸为一体。器身和器底均为铅锡青铜(铜锡铅三元合金),但成分有一定差异,镶嵌的装饰金属片为高铅青铜。铜壶的器底分铸工艺和高铅青铜镶嵌工艺为古代青铜器制作工艺研究提供了重要的新材料。     

Fluid inclusion and isotopic constraints on the origin of ore‐forming fluid of the Jinman–Liancheng vein Cu deposit in the Lanping Basin,western Yunnan,China

Extensive quartz–carbonate–Cu sulfide veins occur in clastic rocks and are spatially related to Paleocene granites in the western border of the Lanping Basin, western Yunnan, China. Abundant aqueous‐carbonic fluid inclusions occur in these veins but their origin is debated. In the Jinman–Liancheng deposit, individual primary inclusion groups contain either exclusively liquid‐rich inclusions (Gl), or coexisting liquid‐rich and vapor‐rich inclusions (Glv). Microthermometry and estimate of CO₂ content indicate that type Gl inclusions either have homogenization temperatures (Th) 238–263°C and contain c. 3.9–5.5 mole % CO₂, or have Th 178–222°C and contain c. 1.6–3.2 mole % CO₂. Type Glv inclusions are thought to represent samples of fluid unmixing that occurred at 183–218°C. At that time, the liquid phase in the unmixing fluid may contain c. 2.0–3.3 mole % CO₂. As such, the correlation of CO₂ content with Th for type Gl inclusions is thought to be caused by fluid unmixing with decreasing temperature and subsequent CO₂ escape. δ¹⁸O and δD values of the parent water mainly fall in the field below that of primary magmatic water, indicative of fluid derivation from degassed (in open system) magmatic water, with no contributions from basinal or meteoric water. Initial Sr isotopic compositions of hydrothermal carbonates suggest that the fluid was magmatic, probably derived from the Paleogene granites. δ¹³C_PDB values (?4‰ to ?7‰) of the hydrothermal carbonates and δ³⁴S_V‐CDT values of sulfides (mainly ?11‰ to +5‰) indicate that the carbon and sulfur can be derived from (degassed) magma and/or nonmagmatic sources. The CO₂‐rich and magmatic‐water‐derived fluid at Jinman–Liancheng differs from the CO₂‐poor and basinally derived fluid in sediment‐hosted stratiform Cu (SSC) deposits, which suggests that there are no genetic linkages between the vein Cu and SSC deposits in the Lanping Basin.     

Labour in Global Value Chains: Work Conditions in Football Manufacturing in China,India and Pakistan

A critical challenge facing developing country producers is to meet international labour standards and codes of conduct in order to engage in global value chains. Evidence of gains for workers from compliance with such standards and codes remains limited and patchy. This article focuses on the global football industry, a sector dominated by leading global brands that manage dispersed global value chains. It assesses the working conditions for football stitchers engaged in different forms of work organization, factories, stitching centres and home‐based settings in Pakistan, India and China. It draws on detailed qualitative primary field research with football‐stitching workers and producers in these three countries. The article explains how and why work conditions of football stitchers differ across these locations through an analytical framework that interweaves both global and local production contexts that influence work conditions. In doing so, it argues that current debates on the role of labour in global value chains have to go beyond a narrow focus on labour standards and corporate social responsibility compliance and engage with economic, technological and social upgrading as factors that could generate sustained improvements in real wages and workers’ conditions.     

A new species of the aphid family Burmitaphididae (Hemiptera: Sternorrhyncha: Aphidomorpha) from Upper Cretaceous Burmese amber

Liu, X., Qiao, G.X., Yao, Y. & Ren, D., 28 March 2019. A new species of the aphid family Burmitaphididae (Hemiptera: Sternorrhyncha: Aphidomorpha) from Upper Cretaceous Burmese amber. Alcheringa 43, 455–460. ISSN 0311-5518

A new species of extinct aphids is reported based on a fossil specimen with a relatively complete body and broken wings from Upper Cretaceous Burmese amber. Vasteantenatus reliquialaus sp. nov. (Hemiptera: Aphidomorpha: Burmitaphididae) differs from other burmitaphidids in having antennae distinctly longer than the body. The diagnosis of Burmitaphididae is emended, and a key to all species of the family is provided

重庆地区出土青铜器铅同位素比值研究

青铜器矿料来源和产地研究,是青铜时代至关重要的考古问题,也是考古的重点和难点之一.通过比较青铜器样品和矿床的Pb同位素分析数据,可以进行青铜金属原料来源的产地研究.为此,本工作利用MAT262固态离子源型质谱仪对重庆地区云阳李家坝遗址,涪陵小田溪墓群,万州大坪墓群,开县余家坝遗址东周时期巴地青铜器的铅同位素进行了测定和比值研究.结果显示其中合金中铅都为普通铅,而非放射性成因铅.实验数据反映出206Pb/204 Pb比值分布在17.4630 ～ 18.6960,207 Pb/204 Pb比值分布在15.5573 ～ 15.8490,208 pb/204 Pb比值分布在36.7828 ～39.3869,除了两个数据外,大部分器物铅同位素比值分布范围几乎重叠,显示了稳定铅源的存在.此外,这批数据与滇川黔铅锌多金属成矿区的底苏和大梁子矿床数据分布范围相近,局部重合,表明其铅料来源与这一地区有着一定的关系.实验结果反映了重庆地区东周青铜器群在铅料来源上具有同一性和连续性,说明了巴人在春秋时期就已经建立了独立的青铜冶铸业,一直延续到战国时期.     

Writing city history at the grassroots level: jiedaozhi and their research value

Chinese local gazetteers (difangzhi) have been long recognized as an important primary source for the study of local history. Since the 1990s, in addition to projects to publish provincial, city, and county gazetteers, local gazetteers for villages, city districts, and city neighborhoods and streets (jiedao) have also been compiled. This paper focuses on one particular genre of these newly emerged local gazetteers, the city sub-district gazetteer or street gazetteers (jiedaozhi). We track their development, and discuss their characteristics and their research value for Chinese studies. We show that jiedaozhi open windows into grassroots society in urban areas, which may stimulate new research directions in Chinese studies.
