U-Pb zircon dates from volcanic ash beds within the Doushantuo Formation (China) indicate that its deposition occurred between 635 and 551 million years ago. The base records termination of global-scale Marinoan glaciation is coeval with similar dated rocks Namibia, indicating synchronous deglaciation. Carbon isotopic sequence-stratigraphic data imply spectacular animal fossils are for most part younger than 580 old. uppermost contains a pronounced negative carbonate carbon excursion, which...
High-precision geochronologic dating constrains probable causes of Earth's largest mass extinction.
The Meishan section across the Permian-Triassic boundary in South China is most thoroughly investigated world. A statistical analysis of occurrences 162 genera and 333 species confirms a sudden extinction event at 251.4 million years ago, coincident with dramatic depletion delta13C(carbonate) an increase microspherules.
The mass extinction at the end of Permian was most profound in history life. Fundamental to understanding its cause is determining tempo and duration extinction. Uranium/lead zircon data from Late Early Triassic rocks south China place Permian-Triassic boundary 251.4 +/- 0.3 million years ago. Biostratigraphic controls strata intercalated with ash beds below indicate that Changhsingian pulse end-Permian extinction, corresponding disappearance about 85 percent marine species, lasted less than...
The Global Stratotype Section and Point (GSSP) for the boundary between Capitanian Wuchiapingian stages, also Guadalupian Lopingian Series is defined at First Appearance Datum (FAD) of conodont Clarkina postbitteri base Bed 6k in Penglaitan along Hongshui River Guangxi Province, South China.This point within a chronomorphocline from hongshuiensis to C. dukouensis nearly coincides with Middle-Upper Absaroka Megasequence as such documented continuously deposited carbonate lowstand succession...
Abstract. An online air pollutant tagged module has been developed in the Nested Air Quality Prediction Model System (NAQPMS) to investigate impact of local and regional sources on pollutants Beijing during Campaign Research 2006 (CAREBeijing-2006). The NAQPMS model shows high performance simulating sulfur dioxide (SO2), particulate matter (PM10), nitrogen (NO2), ozone (O3) with overall better agreements observations at urban sites than rural areas. With module, contributions from surface...
Abstract The Ediacaran Doushantuo Formation in South China is a prime target for geobiological investigation because it offers opportunities to integrate chemostratigraphic and paleobiological data. Previous studies were mostly focused on successions shallow‐water shelf facies, but data from deep‐water are needed fully understand basinal redox structures. Here, we report δ 13 C carb , org 34 S pyr CAS 15 N sed drill core of the fossiliferous Lantian Formation, which equivalent Formation. Our...
Abstract: The Guadalupian–Lopingian boundary stratotype at Penglaitan, and the nearby Tieqiao section, near Laibin, South China, record a series of major environmental changes within Jiangnan Basin during Mid-Permian biotic crisis. sequence-stratigraphic, petrographic palaeontological these sections has been studied associated strontium isotopic fluctuations have assayed. Mass extinction fusulinid foraminifers is most clearly in time with onset volcanism relative sea-level fall that led to...
Studies of the end-Permian mass extinction have suggested a variety patterns from single catastrophic event to multiple phases. But most these analyses been based on fossil distributions localities. Although sections may simplify interpretation species diversity, they are susceptible bias stratigraphic incompleteness and facies control preservation. Here we use data set 1450 18 fossiliferous in different paleoenvironmental settings across South China northern peri-Gondwanan region, integrate...
Abstract The Lopingian represents the last epoch of Palaeozoic Era and is bracketed by two severe biotic mass extinctions associated with dramatic environmental changes. Epoch lasted about 7 millions years was also large volcanic eruptions Emeishan volcanics at base Siberian traps top. Considerable data have accumulated recently in this paper we attempt to summarize these findings a high‐resolution (Late Permian) timescale that integrates currently available multiple biostratigraphic,...
Abstract. Through several years of development, the city Lhasa has become one most populated and urbanized areas on highest plateau in world. In process urbanization, current potential air quality issues have been gradually concerned. To investigate status pollution Lhasa, various gas pollutants including NOx, CO, SO2, O3, were continuously measured from June 2012 to May 2013 at an urban site (29.40° N, 91.08° E, 3650 m a.s.l.). The seasonal variations primary exhibited a peak November...
Abstract Reconstructions of ancient sulfur cycling and redox conditions commonly rely on isotope measurements sedimentary rocks minerals. Ediacaran strata (635–541 Ma) record a large range values in bulk difference (Δ34S) between carbonate-associated sulfate (δ34SCAS) pyrite (δ34Spy), which has been interpreted as evidence marine reservoir size change space time. However, δ34Spy could be misleading because forms under syngenetic, diagenetic, metamorphic conditions, differentially affect its...
