Summary: In this paper, the researchers demonstrate that the Shang period smelting slags from Yingcheng contain highly radiogenic lead (HRL), and the copper ores could have been acquired from Luzudong and Bukou. This is the first discovery of HRL in Shang period smelting slags. The lead isotope signals from Yingcheng match well with those from Middle Shang period bronzes, indicating the possibility that Laiwu could be a source area for metals with HRL at the time.

Summary: The study found that there is no direct evidence to prove that HRL metal in the Hanzhong Shang bronzes originates from the Qinling Mountains, making it difficult to determine if most bronzes used local metal resources. An alternative argument suggests that the HRL used in Hanzhong may have come from the Shang dynasty, reflecting a unified system of metal resource allocation centered on the Shang kingdom.

Summary: This study demonstrates a seasonal pattern of anthropogenic lead transport from the Indo-Gangetic Plain to the Himalayas, with enhanced transport coinciding with higher summer temperatures. Over 50% of lead in Himalayan aerosols originates from the resuspension of historic lead derived from phased out leaded gasoline, underscoring the importance of legacy lead stored in the Indo-Gangetic Plains.

Summary: This study used non-destructive scientific analysis methods to study a bronze wine vessel from the Shang dynasty in China, which is part of the East Asian Collection at the Museum of Applied Arts and Sciences in Sydney, Australia. Gamma spectrometry, neutron-computed tomography, and PIXE spectroscopy were used to gain insights into the structure and composition of the artifact and prove its authenticity. The techniques revealed the elemental composition, porosity, thickness, and alloy used in the vessel, providing valuable information about the craftsmanship and technology of the Shang dynasty.

Summary: This study focuses on the bronzes of the Han Dynasty excavated from Xiangyang, Hubei Province, analyzing their composition using metallographic microscopy, SEM-EDS, and MC-ICP-MS. The results suggest that the appearance of low-tin vessels in Xiangyang during the Han Dynasty is likely due to both cost reduction and advancements in bronze production techniques. Lead isotope analysis indicates that the minerals used for bronzes in Xiangyang were sourced from the Eastern Zhou period and later from the Nanyang area. Additionally, some bronzes may have used minerals from southern Anhui and Yunnan, suggesting a customized circulation to the Xiangyang area.

Summary: The Han burials in the Wuchuan region of the northeast Yungui Plateau are known for the cinnabar grains placed within. Many bronze grave goods are morphologically similar to those in the Central Plains, providing clues for studying the immigrants from the Central Plains during the Qin and Han Dynasties. By combining lead isotope and alloy composition analyses, the researchers were able to classify Wuchuan bronzes into three provenance groups. The study indicates that while the early Western Han Dynasty bronze wares in Wuchuan were imported from northern China, the Eastern Han Dynasty bronzes were likely produced locally using the metal resources from the Yungui Plateau.

Summary: In this study, lead isotopic analysis was conducted on 54 bronzes dating to the Western Han Dynasty, which indicated a narrowing variation in lead isotopes from the early to late Western Han Dynasty. The sources of lead during the early Western Han Dynasty were complicated, while those used in the middle to late period were more uniform and consistent with minerals used in mirrors from Chang'an and Japan, most likely from the western Henan area. This shift in economic strategy from free operation to state monopoly is reflected in the lead isotopes.

Summary: The behavior of radiogenic isotopes during the melting of metasediments is influenced by the source and temperature of the melt. During the melting process, muscovite preferentially enters the melt relative to plagioclase, resulting in variation in Sr isotopes. In addition, the incomplete dissolution of zircon and the higher crystallization temperature result in the leucosome having Nd and Hf isotopes compositions closer to the source.

Summary: The late Cambrian tonalite-trondhjemite association in the eastern segment of North Qilian suture zone provides important insights into the sub-arc magmatic process and tectonic evolution, with evidence suggesting that these rocks were likely formed in a continental-arc rifting environment. The geochemical characteristics of these rocks indicate minimal contribution from the continental crust, with a common basaltic parental magma undergoing crystal fractionation in the early stage of subduction due to slab rollback.

Summary: The eruption of large igneous provinces has significant geodynamic effects on overriding plates. Seamount chains indicate a change in the drifting direction of the Pacific Plate during the Early Cretaceous. Magnetic anomalies also suggest changes in the orientations of spreading ridges. The eruption of the Ontong Java plume head uplifted the southeastern corner of the Pacific Plate and pushed its eastern part northward. Meanwhile, the western part of the Pacific Plate was subducting beneath the eastern Asian Continent. These forces combined to rotate the Pacific Plate anticlockwise and change its drifting direction.

Summary: The Fangshan intrusive suite is a composite pluton in the North China Craton formed through incremental assembly of small magma batches. Zircon U-Pb dating revealed that each intrusive unit crystallized over a prolonged period between 132.5 and 128.7 Ma, at upper-crustal levels. Different zircon types in mafic enclaves suggest diverse crystallization environments and processes, shedding light on the complex evolution of the magmatic system.

Summary: Carbon dioxide has been increasing in the atmosphere since the industrialization, resulting in global warming, which in turn enhanced methane emissions from permafrost regions. However, methane emitted into the atmosphere is quickly oxidized, such that the intensity and threat of methane emission in the past are severely underestimated.

Summary: During the early Cenozoic, the atmospheric CO2 concentration experienced a rapid increase, reaching values 5-10 times higher than present levels, followed by a continuous decline. The cause of this phenomenon remains uncertain. This study suggests that the initiation of west Pacific plate subduction, triggered by collision in the Tibetan Plateau, coincided with this tipping point. The subduction zones in the Pacific had deeper water depths, resulting in less carbonate subduction, while the Neo-Tethys had shallower depths, leading to more carbonate subduction. Furthermore, the west Pacific subduction zones had higher volcanic ash emissions, which helped consume CO2.

Summary: The Hawaiian-Emperor seamount chain displays two parallel volcanic trends, Loa and Kea, which have been studied extensively. However, the increased eruption rate and southward bending of the chain remain unexplained. This study proposes a plume-plume interaction model, where the Loa trend represents an emerging plume head southeast of the original Hawaiian plume tail, and the interaction between these two plumes is responsible for the southward bending and increased eruption rate. This double-plume scenario may also play a role in the formation of other hotspot tracks.
