Abstract The exhumation mechanism of high‐pressure ( HP ) and ultrahigh‐pressure UHP eclogites formed by the subduction oceanic crust (hereafter referred to as eclogites) is one primary uncertainties associated with factory. phase relations densities MORB compositions are modelled using thermodynamic calculations over a P–T range 1–4 GPa 400–800 °C, respectively, in NCKFMASHTO Na 2 O – CaO K FeO MgO Al 3 SiO H TiO Fe system. Our modelling suggests that mineral assemblages, proportions...
Developing high-efficient and easy-to-recover adsorbents for the removal of toxic metals in water is imperative, although it poses a huge challenge. In this study, sulfur-functionalized metal-organic framework was incorporated into Ca-alginate/polyacrylic acid granulates as an effective adsorbent (abbr. CPZ-SH) Cu2+ Cd2+ removal. The physicochemical properties obtained CPZ-SH were determined by integrated characterization techniques (e.g., FTIR, XRD, SEM). environmental effects solution pH,...
Abstract Lawsonite is an important hydrous mineral that stable at low‐temperature ( LT ) and high‐ to ultrahigh‐pressure HP – UHP conditions in subducted slabs. The occurrence/absence of lawsonite eclogite a significant constraint for the construction metamorphic, tectonic fluid/melt evolution histories HP–UHP terrane. However, very rarely preserved natural eclogites, accurate judgment its former existence challenge petrologists. At present, whether has ever existed lawsonite‐absent mainly...
The unique reactivity of in situ generated propargylic para-quinone methides as a new type five-carbon synthon has been discovered by novel bismuth(III)-catalyzed tandem annulation reaction. This 1,8-addition/cyclization/rearrangement cyclization cascade reaction is characterized unusual structural reconstruction 2-vinylphenol, involving cleavage the C1'═C2' bond and formation four bonds. method provides convenient mild approach to generate synthetically important functionalized...
Chiral ketones and their derivatives are useful synthetic intermediates for the synthesis of biologically active natural products medicinally relevant molecules. Nevertheless, general broadly applicable methods enantioenriched acyclic α,α-disubstituted ketones, especially α,α-diarylketones, remain largely underdeveloped, owing to easy racemization. Here, we report a visible light photoactivation phosphoric acid–catalyzed alkyne-carbonyl metathesis/transfer hydrogenation one-pot reaction...
Garnet orthopyroxenites of the Maowu mafic–ultramafic body occur in coesite-bearing paragneisses Dabieshan ultrahigh-pressure (UHP) metamorphic complex. We have distinguished six stages metamorphism based on integrated mineralogical–petrological investigations: M1 – high-T/low-P (˜1.4 GPa, ˜850°C); M2 low-T/low-P ˜750°C); M3 low-T/high-P (2.1–2.5 740–760°C); M4 UHP (5.3–6.3 ˜800°C); M5 early retrogression (<3 >750°C); M6 late (<2.3 <670°C). Detailed textures and mineral compositions indicate...
In order to study the temporal and spatial distribution characteristics of atmospheric pollutants in cities (districts counties) Chengdu–Chongqing Twin-city Economic Circle (CCEC) provide a theoretical basis for pollution prevention control, this paper combined Ambient Air Quality Standards (AAQS) WHO Global Guidelines (GAQG) evaluate used correlation determine key areas. The results showed that CCEC presents certain law, which was consistent with air transmission channels. Except...
The upper crustal anisotropy of Yunnan area, SE margin Tibetan Plateau, is investigated by measuring the shear wave splitting local earthquakes. mean value measured delay times 0.054 s and far less than that from Pms analysis, indicating contributed mostly mid-lower crust. fast polarization directions are sub-parallel to maximum horizontal compression while stations near fault zones show fault-parallel directions, suggesting both stress geological structure contribute crust anisotropy....
The southeastern margin of the Tibetan Plateau (SETP) presents highest level seismicity in mainland China. To understand this region, a new seismic experiment is carried out based on tomographic inversion P- and S-wave arrival times from regional earthquakes recorded by 49 stations Yunnan Province Southwest In study, we reduce extreme disproportionality data distribution using an events combination method, use to construct reference velocity model. Checkerboard tests odd/even are assess...
SUMMARY Knowledge about the spatial contact relationship between Yangtze Plate and eastern Qinling-Dabie orogenic belt can not only provide a scientific basis for exploration of mineral resources, disaster prevention earthquake prediction in region, but also play an important role reconstructing geological process central belt. Hence, high-resolution lithospheric velocity model is essential to address these problems. In this study, using waveform data from 48 stations Hubei Province adjacent...
Abstract Red slipped and painted wares (RSW RPW) were manufactured to cook, serve, or store foods liquids in the middle Yangtze River valley (MYRV) of China some 8500 7800 years ago, respectively. Their primary use narrowed down serving drinking Upper Qujialing (5300–4500 cal BP) Shijiahe (4500–4200 periods when initial states ( bang guo ) took shape developed region. The increasing social complexity MYRV correlated with formation community neighborhood identity through rituals...
SUMMARY The Qinling–Dabie orogenic belt, which contain the arc-shaped Dabbashan orocline and is world's largest belt of HP/UHP metamorphic rocks, formed by a long-term complex amalgamation process between North China Block Yangtze Block. To understand collision processes tectonic evolution, we constructed 3-D S-wave velocity model from surface to depth ∼120 km in eastern Qinling-Dabie its adjacent region inverting 5–70 s phase dispersion data Rayleigh waves extracted ambient noise data.
