The eastern equatorial Pacific cold tongue (EEP-CT) today asserts a vital influence on ocean-atmosphere CO2 exchange and global climate patterns. Here, we report similar in the Late Ordovician peri-Gondwana region during drastic greenhouse-icehouse swings first mass extinction. Paleontological, sedimentological, new stable-oxygen-isotope data from conodont apatite point to change warm-water cool-water tropical depositional environments South China plate Early Ordovician. This apparently...
The end Ordovician mass extinction (EOME) was the second most severe biotic crisis in Phanerozoic, and has been widely linked to a major glaciation. However, robust geochronology of this interval is still lacking. Here we present four successive high-precision zircon U–Pb dates by isotope dilution thermal ionization spectrometry (ID-TIMS) for biostratigraphically well-constrained K-bentonites continuous Ordovician-Silurian boundary section at Wanhe, SW China. They include 444.65 ± 0.22 Ma...
Tremadocian (Lower Ordovician) carbonate rocks were collected from the Xiangshuidong section in Hubei Province, South China, and analyzed for conodont biostratigraphy. A total of 24 species belonging to 16 genera recovered Nantsinkuan Fenhsiang formations. Three zones are recognized based on this material, i.e., Rossodus manitouensis Zone, Colaptoconus quadraplicatus - Paltodus pristinus Assemblage deltifer ascending order. biostratigraphic gap, corresponding Cordylodus lindstromi angulatus...
Abstract One of the few and most complete records MDICE (Middle Darriwilian Isotope Carbon Excursion) is herein documented from Baltoscandia. Based on a core section penetrating condensed Lower–Middle Ordovician succession (~46 m) island Öland, southeastern Sweden, we provide an integrated scheme for carbon isotope chemostratigraphy (313 samples) conodont biostratigraphy (29 this period. The carbonate in Tingskullen 12 zones 6 subzones, including Oepikodus evae, Trapezognathus diprion,...
Based on the Tingskullen drillcore, we present first continuous carbon isotope stratigraphy from Lower–Middle Ordovician "orthoceratite limestone" of Öland, Sweden. The extremely condensed Tremadocian and Floian stages include large gaps as well Ceratopyge Regressive Event widespread Evae transgression accompanied by prominent shifts in δ 13C record. Dapingian Darriwilian are characterised low sedimentation rates a relatively complete sedimentary A total 99 whole-rock samples were analysed...
The Great Ordovician Biodiversification Event (GOBE) represents the greatest increase in marine animal biodiversity ever recorded. What caused this transformation is heavily debated. One hypothesis states that rising atmospheric oxygen levels drove biodiversification based on premise animals require for their metabolism. Here, we present uranium isotope data from a Middle carbonate succession shows steepest rise generic richness occurred with global redox stability. Ocean oxygenation ensued...
Abstract Wind and solar energy are crucial for meeting the growing demand mitigating impact of climate change, their sources show a climate‐dependence. Here, based on outputs from two regional models (RCMs) driven by three global within Coordinated Regional Climate Downscaling Experiments‐East Asia (CORDEX‐EA‐II), effects future change wind power density (WPD) photovoltaic potential (PVP) in China under Representative Concentration Pathway (RCP) 2.6 scenario RCP8.5 comprehensively...
We have investigated the interband electron transitions in a GaNAs/GaAs single quantum well (QW) by photoluminescence and absorption spectra. The experimental results show that dominant at low temperature high excitation intensity originates from within GaNAs layer. transition energy for QWs with different widths can be fitted if type-II band line up of is assumed.
A survey on the (palaeo-) diversity of Lower and Middle Ordovician conodont faunas from Yichang Region, Hubei Province, Central China is presented.Analysis number species through time shows richness cyclical developed in succession -varying low to high.One major peak recorded mid late Floian Stage (Oepikodus evae Zone, stage slice Fl 2, Ordovician), where 33 are lower unit Dawan Formation.A smaller but second high found Darriwilian (Lenodus variabilis Zone; Da Ordovician) with a maximum 23...
Periodicity fluctuations of layer thickness and composition in a superlattice not only decrease the intensity, they also broaden width satellite peaks x-ray diffraction pattern. In this letter, we develop method that is dependent on to assess periodicity quickly. A linear relation magnitude fluctuations, peak order has been derived from kinematical theory. By means method, strained (GaNAs)1(GaAs)m superlattices grown GaAs substrates by molecular beam epitaxy have studied. Distinct indicate...
The Ordovician Lagerstätten record substantial amounts of excellent preservation and soft-bodied fossils during the Great Biodiversification Event (GOBE). However, few are known from Lower Ordovician, most which preserved in restricted environments high-latitude regions. Here, we report on a new tropical Lagerstätte, Liexi fauna, has been recently discovered carbonate succession within Madaoyu Formation western Hunan, South China. It contains variety soft tissues, as well rich shelly...
The Lower and Middle Ordovician of the Yangtze Platform, China, is characterized by a sedimentary succession dominated carbonate rocks. Three sections spanning Nantsinkuan/Lunshan, Fenhsiang, Hunghuayuan, Dawan/Zitai formations, corresponding to Tremadocian–Dapingian in age, have been sampled for high-resolution δ 13 C chemostratigraphy (542 samples total). Our new data reveal five tie-points with potential global correlation: (1) positive excursion lower Nantsinkuan Formation within...
