However, the classical ID-TIMS technique is laborious and time-consuming because the purified Rb and Sr fractions must be individually loaded onto different independent filaments due to severe 87Rb isobaric interference on 87Sr.. To overcome this issue, we developed a new method whereby Rb and Sr were sequentially measured by TIMS on the same filament, without venting, to obtain both ratios of 87Rb/86Sr and 87Sr/86Sr and concentrations of Rb and Sr. Article Title: The initial solar system abundance of 60 Fe and early core formation of the first asteroids Article Snippet: Elution curve of column chemistry using Article Title: Revisiting the Mg isotopic systematics of siliciclastic components of sediments and sedimentary rocks: A new geochemical proxy of continental weathering in Earth’s history Article Snippet: The Mg isotopic compositions of siliciclastic components (δMgsili) of sediments and sedimentary rocks have been commonly used to constrain the intensity of continental weathering, based on observations of, (1) an upward enrichment of Mg in modern weathering profiles, (2) preferential uptake of Mg in soil clays, and (3) general positive correlations between weathering intensities and δMgsili values.. However, not all weathering profiles display an upward increase of δ Mgsili, and not all soil clays enrich in Mg, complicating the interpretations of δMgsili data of sediments and sedimentary rocks.. To further explore the controls of δMgsili of sediments and sedimentary rocks, here we measured δ Mgsili, mineralogical compositions and major element compositions of deep sea sediments from South China Sea (SCS) and carbonate rock samples from two late Paleozoic sections in South China. Article Title: Constraining the terminal Ediacaran seawater chemistry by Mg isotopes in dolostones from the Yangtze Platform, South China Article Snippet: The advent of animal biomineralization at the terminal Ediacaran remarkably changed the marine ecological system.. Changed seawater Mg/Ca ratio is considered as an important external trigger for this transition, but the intrinsic relationship between seawater Mg/Ca variation and animal biomineralization is not well constrained due to the lack of reliable archives.. To constrain the coeval seawater chemistry and explore its role in the origin of metazoan biomineralization, we systematically conducted petrographical and geochemical investigations on dolostones from the terminal Ediacaran (~551 Ma) Dengying Formation of the Yangtze Block in South China. Chromatography:Article Title: Garnet’s impact on the petrogenesis of Himalayan leucogranites Article Snippet: This is a PDF of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability.. This version will undergo additional copyediting, typesetting and review before it is published in its final form.. As such, this version is no longer the Accepted Manuscript, but it is not yet the definitive Version of Record; we are providing this early version to give early visibility of the article. Article Title: Magnesium isotopic evidence for staged enhancement of the East Asian Summer Monsoon precipitation since the Miocene Article Snippet: Knowledge of the evolution of the East Asian Summer Monsoon (EASM) provides a valuable opportunity to uncover the dynamic interactions of land-ocean-atmosphere system in the late Cenozoic.. However, the evolutionary history of EASM remains debatable, mainly due to the difficulty in separating EASM precipitation and temperature signals.. In this study, precipitation proxies of Sr/Ca ratio and dMg value in loess secondary calcite (carbonate nodule (NC) and fine carbonate (FC) (grain size < 4 lm)) are further verified, with high precipitation corresponding to high dMgFC but low d MgNC and Sr/CaNC ratio, and vice versa. Purification:Article Title: Geochemical and Chronological Constraints on the Origin and Mantle Source of Early Cretaceous Arc Volcanism on the Gagua Ridge in Western Pacific Article Snippet: The modern western Pacific has developed a number of spreading basins (e.g., the western Philippine Sea and the Parece Vela basin) and arcs (e.g., Izu Bonin and Mariana arcs) since the Cenozoic (Figure 1).. Geochemical studies of the spreading basins and arc volcanic rocks since the 1980s confirmed the existence of an Indian-type (Dupal anomaly) (e.g., Dupré & Allègre, 1983; Hart, 1984) asthenospheric mantle in the northern hemispheric western Pacific mantle, for example, they are within the domain of Indian MORBs on plots of 208Pb/ 204Pb versus 206Pb/ 204Pb and ɛHf versus ɛNd (Flower et al., 2001; Hickey-Vargas, 1998; Woodhead et al., 2012).. However, it remains unclear whether the Indian-type mantle in the western Pacific represents an in situ mantle signature or originated from the Southern Hemisphere caused by the northward asthenospheric flow (Flower et al., 2001; Hickey-Vargas, 1998; Miyazaki et al., 2015; Straub et al., 2009; Zhang et al., 2018).
