Garnet-bearing mafic granulite and amphibolite exposed as lenses, boudins, or interlayers within metasediments in the Qingshigou area, Dunhuang block, southernmost Central Asian orogenic belt, record important information for understanding tectono-metamorphic evolution of subduction collision zones southern belt during mid-Paleozoic. Three stages metamorphic assemblages (M1, M2, M3) are recognized high- medium-pressure amphibolite. In high-pressure granulite, prograde assemblage (M1) is...

Abstract High-resolution SIMS U–Pb dating of metamorphic zircons the TTG gneisses, gneissic granitoid and amphibolites Lushan terrane, Taihua complex, suggests that metamorphism had taken place at least as early ~1.96–1.86 Ga. These new dates, along with reference data, demonstrate southern middle terranes Trans-North China Orogen been involved in continent–continent collision between Western Block Eastern North Craton. This orogenic process started 1.96 Ga lasted late 1.80
Mafic granulite and amphibolite in the Dongbatu Mogutai blocks, middle Dunhuang orogenic belt, northwest China, southernmost Central Asian occur as lenses within matrix of metapelite marble, exhibiting typical block-in-matrix fabrics tectonic mélange. Three stages metamorphic mineral assemblages were identified these lenses. Clockwise pressure-temperature (P-T) paths obtained through geothermobarometry thermodynamic pseudosection modeling, passing from 656 °C 10.9 kbar 830 16.5 to 657 4.9...
Amphibolites in the Shuixiakou area of southern Dunhuang Orogenic Belt, southernmost Central Asian Belt (CAOB), occur as lenses within hornblende-biotite-plagioclase gneiss or pelitic schist, exhibiting block-in-matrix feature tectonic mélange. Three generations metamorphic mineral assemblages (M1, M2, and M3) have been recognized garnet-bearing amphibolite lenses. The prograde assemblage (M1) is documented with inclusion trails (hornblende + plagioclase quartz) garnet porphyroblasts, are...
Abstract Geothermobarometry shows that metapelite samples from Namche Barwa Complex (NBC) reached upper amphibolite to near‐granulite facies during the peak metamorphic stage, with similar conditions of ~700–750°C/8–10 kbar, and then experienced retrograde metamorphism at ~630–700°C/4–7 kbar. In situ monazite laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) U–Th–Pb dating suggests divergent in NBC: on hanging wall Namu–La thrust preserved a continuous record >19–3...
Gabor deconvolution approaches the goal of enhancing seismic resolution by removing propagating wavelet, which could be estimated smoothing magnitude spectrum. Under constant Q theory, it is more reliable to do along hyperbolic trajectories in time-frequency plane. During iteration process ordinary smoothing, any division should necessarily accompanied with an empirical whiten factor. Both modeling work and real data processing this paper show that these factors might smear some useful...
扬子板块的太古宙-古元古代基底出露十分有限,制约了对扬子早前寒武纪地质演化的认识。本次研究对扬子板块西南缘撮科地区的大红山群和昆阳群变沉积岩开展了碎屑锆石原位U-Pb年龄、Hf-O同位素及微量元素研究。测年结果显示,大红山群谐和锆石年龄分布于3092~1786 Ma之间,最年轻碎屑锆石年龄为1786 Ma,限定大红山群最大沉积时代为古元古代晚期。昆阳群谐和锆石年龄分布于2874~1031 Ma之间,最年轻碎屑锆石年龄为1031 Ma,表明昆阳群最大沉积时代为中元古代晚期。除少量较年轻锆石(<1.75 Ga)外,昆阳群和大红山群具有相似的年龄分布特征,两个主要的年龄峰为2.0~1.85 Ga和2.4~2.2...
Abstract The northern Alxa region is located in the central segment of southern Central Asian Orogenic Belt. Many controversies and deficiencies still exist regarding magma source characteristics, petrogenesis tectonic regimes during late Palaeozoic – early Mesozoic period within this region. This study presents whole-rock compositions zircon U–Pb Lu–Hf isotopic data for three I- A-type granitic plutons occurring Haerchaoenji Chahanhada I-type granitoids yielded 206 Pb– 238 U ages 245 ± 5 Ma...
Summary Gabor deconvolution is acknowledged as an effective nonstationary method which can simultaneously remove the source signature and attenuation effects. Under constant Q theory, contours track along hyperbolic trajectories in time-frequency plane, smoothing these would lead to more reasonable estimation on attenuation, wavelet reflectivity. Furthermore, division operation necessitated form operator, pre-whitening factors are always used enhance stability. However, pre-whiting factor so...

Based on published study, "the contents chemical mineral compositions suspended particulate materials Yangtze River their geological environmental implications" by Ding Tiping, CaO, MgO, calcite dolomite collected from 25 sampling points mainstream 13 tributaries 4 campaigns during 2003-2007 were used to calculate total inorganic sink (TCS) capacity...
Triclocarban (TCC) is an antimicrobial agent commonly used in many household and personal care products, has been found persistent the aquatic environment. Here we elucidate kinetics mechanism of TCC degradation during chlorination process by density functional theory (DFT) calculation experimental verification. Results showed that chlorine two forms (HOCl OCl-) reacted with via Cl-substitution, dechlorination, OH-substitution C—N bond cleavage pathways. The reactivity OCl- (2.80 × 10-7 M-1...
