The purpose of the “Made in China 2025” strategy is to enhance innovation capabilities local manufacturing industry and achieve green sustainable development. role development a hotspot academic research, though only few studies have analyzed interaction between technology efficiency its external capabilities. This study used 2011–2017 Chinese A-share listed companies as samples discuss whether regional can promote improvement efficiency. results showed that significant spatial correlation...
Zircon is a principal source of zirconium and hafnium, as well key mineral both for petrogenetic modeling age dating. Although zircon occurrences have been reported from hydrothermal systems, detailed studies on that crystallized entirely saturated fluid are rare. Here we report crystals dated at about 1911 Ma boiling high-salinity H2O-CO2 with inclusion homogenization temperatures 295 to 325 °C the corresponding pressure 71 bar. These were then overprinted by two stages veins 1864 528 Ma....
Marine phosphatization events cause episodic carbonate fluorapatite (CFA) precipitation on seamounts, and are commonly linked to growth hiatuses in ferromanganese (Fe-Mn) crusts, provide critical archives for reconstructing past ocean oxygen dynamics phosphorus cycling due the tight relationship with oceanic minimum zones(OMZs). However, complete record of these their paleoenvironmental significance remains poorly understood, large part poor age constraints. Here, we apply U-Pb dating CFA...
Objective To evaluate the health systems efficiency in China and Association of Southeast Asian Nations (ASEAN) countries from 2015 to 2020. Design Health analysis using data envelopment (DEA) stochastic frontier approach analysis. Setting ASEAN countries. Methods DEA-Malmquist model SFA were used analyse system among countries, Tobit regression was employed factors affecting these Results In 2020, average technical efficiency, pure scale 10 countries’ 0.700, 1 0.701, respectively.

In deep sea sediments, rare earth elements and yttrium (REYs) are predominantly carried by bioapatite Fe-Mn (oxyhydr)oxides. According to recent studies, REYs can migrate into after the dissolution of However, REY migration mechanism from (oxyhydr)oxides still unclear. Here, we integrated in situ trace element Nd isotope analyses elucidate geochemical characteristics fish tooth-bearing nodules Northwest Pacific Ocean. Our nodule samples be classified different morphological types periods...
This contribution presents new U-Pb geochronological data and attempts to elucidate the complex evolution history of various garnet types identified from two kimberlite pipes in Wafangdian diamond mining district, southern Liaoning Province. These calcic garnets are dominated by andradite with relatively low proportions schorlomite, grossular pyrope. Abundant euhedral subhedral, highly brecciated phenocrysts hosted LN30 "carbonatite-like" samples yield a lower-intercept age 459.3 ± 3.4 Ma,...
The giant Beiya Au skarn deposit and Machangqing porphyry Cu-Mo-(Au) are located in the middle part of Jinshajiang–Ailaoshan alkaline metallogenic belt. is largest China, whilst comprises a well-developed porphyry-skarn-epithermal mineral system. In this paper, we present new allanite U-Th-Pb ages trace element geochemical data from two deposits discuss their respective metallogenesis. Based on assemblage, texture Th/U ratio, likely hydrothermal rather than magmatic. Laser...
China has gradually become an important world investor with the implementations of its “Going Global” and “Belt Road” strategy initiatives. Indonesia is world’s largest archipelagic country, economy ASEAN (Association Southeast Asian Nations). Therefore, node for China’s implementation initiative. However, existing research results regarding OFDI (Outward Foreign Direct Investment) in have indicated that little focus been placed on distribution patterns determinants at provincial levels. In...
Recent studies have shown that the rare earth elements and yttrium (REY)-rich deep-sea sediments often contain abundant phillipsite, which is considered as an indicator mineral for REY-rich sediments. However, phillipsite contains very low REY content, coexistence of enrichment generally explained by sedimentation rate in deep sea environment. Whether has capacity to enrich why it REY-poor still unclear. Phillipsite also present ferromanganese nodules surface sediments, yet whether there any...
Marine phosphatization events cause episodic carbonate fluorapatite (CFA) precipitation on seamounts, and are commonly linked to growth hiatuses in ferromanganese (Fe-Mn) crusts. However, the complete record of these their paleoenvironmental significance remains poorly understood, large part due poor age constraints. Here, we apply U-Pb dating CFA Fe-Mn crusts from Western Pacific seamounts. These data exhibit good alignment with Sr isotope ages, revealing six potential events. This...
Colloform pyrite with core-rim texture is commonly deposited in carbonate platforms associated the sulfide ores such as Caixiashan Pb–Zn deposit. However, genesis of colloform deposits, its growth controls and their geological implication are insufficiently understood. Integration in-situ trace element SIMS sulfur isotopes has revealed geochemical variations among these layers. These occur residual phases aggregates, cores made up very fine-grained anhedral particles, some rims being...
