1High-Temperature Metamorphism, Anataxis and Tectonic Evolution of a Mafic Granulite from the Eastern Himalayan Orogen显示文摘The Himalayan Orogen, resulting from the Tertiary collision of Indian and Asian continents, is a natural laboratory for studying metamorphism, partial melting and granite formation of collisional orogens. However, metamorphic and anatectic conditions and timescales of meta-mafic rocks in the Greater Himalayan Sequences(GHS) in the east-central Himalaya remain controversial. In this paper, we conduct a study of petrology and geochronology of mafic granulite from the Eastern Himalayan Syntaxis(EHS). The mafic granulite with abundant leucosome bands occurs as layers within felsic granulites and is well deformed. The granulite consists of garnet, plagioclase, amphibole and quartz with minor clinopyroxene, orthopyroxene, biotite, rutile, titanite and ilmenite. The garnet has growth compositional zoning and contains abundant mineral inclusions in its core. Peak metamorphic mineral assemblage of the granulite is garnet, amphibole, plagioclase, quartz, clinopyroxene and rutile, recording a high-pressure(HP) and high-temperature(HT) peak-metamorphism under conditions of 14–15.5 kbar and 780–790℃ in the presence of melt. The reconstructed clockwise P-T path is characterized by an early heating and burial prograde metamorphism, and late isothermal and cooling decompression retrogression. The granulite witnessed a long lasting HT metamorphism, partial melting and melt crystallization process which began at ca. 39 Ma and lasted to ca. 11 Ma. The present study shows that various high-grade rocks of the GHS in the EHS core experienced similar metamorphic conditions and P-T-t paths, indicating that they occurred as a coherent slab during the subduction and exhumation of Indian lithosphere. The significant melts generated during the prograde metamorphism of the GHS rocks not only contributed to the formation of the Himalayan leucogranite, but also resulted in the rheological weakening and ductile flow of the thickened lower crust of the Himalayan Orogen.Zeming Zhang Huixia Ding Xin Dong Zuolin Tian Dongyan Kang Hongchen Mu Shengkai Qin Yuanyuan Jiang Mengmei Li 2018Journal of Earth Science2018,29,5:7

3Intra-abdominal aortic balloon occlusion in the management of placenta percreta显示文摘Background:Massive bleeding is the main concern for the management of placenta percreta(PP).Intra-abdominal aortic balloon occlusion(IABO)is one method for pelvic devascularization,but the efficacy of IABO is uncertain.This study aims to investigate the outcomes of IABO in PP patients.Methods:We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015.PP cases with/without the use of IABO were analyzed.Propensity score matching analysis was performed to reduce the effect of selection bias.Postpartum hemorrhage(PPH)and the rate of hysterectomy,as well as neonatal outcomes,were analyzed.Results:One hundred and thirty-two matched pairs of patients were included in the final analysis.Compared with the control group,maternal outcomes,including PPH(68.9%vs.87.9%,χ^(2)=13.984,P<0.001),hysterectomy(8.3%vs.65.2%,χ^(2)=91.672,P<0.001),and repeated surgery(1.5%vs.12.1%,χ^(2)=11.686,P=0.001)were significantly reduced in the IABO group.For neonatal outcomes,Apgar scores at 1 minute(8.67±1.79vs.8.53±1.68,t=-0.638,P=0.947)and 5 minutes(9.43±1.55vs.9.53±1.26,t=0.566,P=0.293)were not significantly different between the two groups.Conclusions:IABO can significantly reduce blood loss,hysterectomies,and repeated surgeries.This procedure has not shown harmful effects on neonatal outcomes.Weiran Zheng Ruochong Dou Jie Yan Xinrui Yang Xianlan Zhao Dunjin Chen Yuyan Ma Weishe Zhang Yiling Ding Ling Fan Huixia Yang 2022Chinese Medical Journal2022,,4:2

6Two-dimensional silicon-carbon hybrids with a honeycomb lattice: New family for two-dimensional photovoltaic materials显示文摘We predict a series of new two-dimensional(2D) inorganic materials made of silicon and carbon elements(2D SixC1?x) based on density functional theory. Our calculations on optimized structure, phonon dispersion, and finite temperature molecular dynamics confirm the stability of 2D SixC1?x sheets in a two-dimensional, graphene-like, honeycomb lattice. The electronic band gaps vary from zero to 2.5 e V as the ratio x changes in 2D SixC1?x changes, suggesting a versatile electronic structure in these sheets. Interestingly, among these structures Si0.25C0.75 and Si0.75C0.25 with graphene-like superlattices are semimetals with zero band gap as their ? and ?* bands cross linearly at the Fermi level. Atomic structural searches based on particle-swarm optimization show that the ordered 2D SixC1?x structures are energetically favorable. Optical absorption calculations demonstrate that the 2D silicon-carbon hybrid materials have strong photoabsorption in visible light region, which hold promising potential in photovoltaic applications. Such unique electronic and optical properties in 2D SixC1?x have profound implications in nanoelectronic and photovoltaic device applications.ZHANG Jin REN Jun FU HuiXia DING ZiJing LI Hui MENG Sheng 2015Science China(Physics,Mechanics & Astronomy)2015,58,10:1

9The Eocene corundum-bearing rocks in the Gangdese arc, south Tibet:Implications for tectonic evolution of the Himalayan orogen显示文摘The genesis of Liangguo corundum deposit in the southern Gangdese magmatic arc, east-central Himalaya, remains unknown. The present study shows that the corundum-bearing rocks occur as lenses with variable sizes in the Eocene gabbro that intruded into marble. These corundum-bearing rocks have highly variable mineral assemblage and mode. The corundum-rich rocks are characterized by containing abundant corundum, and minor spinel, ilmenite and magnetite, whereas the corundum-poor and corundum-free rocks have variable contents of spinel, plagioclase, sillimanite, cordierite, ilmenite and magnetite. The host gabbro shows variable degrees of hydration and carbonization. The corundum grains are mostly black, and rarely blue, and have minor Fe O and TiO_2. The spinel is hercynite, with high Fe O and low Mg O contents. The corundum-bearing rocks have variable but high Al_2O_3, FeO and TiO_2, and low SiO_2 contents. Inherited magmatic and altered zircons of the corundum-bearing rocks have similar U e Pb ages(~47 Ma) to the magmatic zircons of the host gabbro, indicating corundum-bearing rock formation immediately after the gabbro intrusion. We considered that emplacement of gabbro induced the contact metamorphism of the country-rock marble and the formation of silica-poor fluid. The channeled infiltration of generated fluid in turn resulted in the hydrothermal metasomatism of the gabbro, which characterized by considerable loss of Si from the gabbro and strong residual enrichment of Al. The metasomatic alteration probably formed under Pe T conditions of ~2.2 -2.8 kbar and ~650 -700℃. We speculate that SiO_2, CaO and Na_2O were mobile, and Al_2O_3, FeO, TiO_2 and high field strength elements remained immobile during the metasomatic process of the gabbro. The Liangguo corundum deposit, together with metamorphic corundum deposits in Central and Southeast Asia, were related to the Cenozoic Himalayan orogeny, and therefore are plate tectonic indicators.Zeming Zhang Huixia Ding Xin Dong Zuolin Tian Hongchen Mu Mengmei Li Shengkai Qin Zhixiang Niu Ning Zhang 2018Geoscience Frontiers2018,9,5:0
