The broad-scale environment plays a substantial role in shaping modern marine ecosystems, but the degree to which palaeocommunities were influenced by their is unclear. To investigate how community ecology of early animal we employed spatial point process analyses (SPPA) examine structure seven late Ediacaran (558–550 Ma) bedding-plane assemblages drawn from range environmental settings and global localities. studied exhibit marked differences response component taxa sub-metre-scale habitat...
Abstract Palaeopascichnida is a problematic group of extinct organisms that globally distributed in Ediacaran sequences Avalonia, Baltica, Siberia, South China and Australia. The fossils related to consist serially or cluster-like arranged, millimetre- centimetre-scale globular allantoid chambers, which are characterized by substantial differences preservation, leading no consistent diagnosis for these organisms. Here we integrate morphometric variation, stratigraphic distribution habitat...
Developments in continuous and pulsed laser-heating techniques, finite-element calculations for diamond anvil cell experiments are reported. The methods involve the use of time-resolved (5 ns gated) incandescent light temperature measurements to determine time dependence heat fluxes, while near-IR allow as low 500 K. Further optimization timing laser heating together with sample engineering will provide additional improvements data collection very high P-T experiments.
The deep abiogenic synthesis of hydrocarbons is possible under the conditions asthenosphere. We have found that this process can also occur mineral and thermobaric subducting slabs. investigated hydrocarbon systems at pressures 2.0-6.6 GPa temperatures 250-600 °C. determined lower limit reaction 280-300 °C 2-3 corresponds to a depth 70-80 km during cold subduction. fluid formed in slab migrate upwards through network faults fractures form petroleum deposits.
In the course of studying modern halotolerant microbial mats in salterns near village Kervalet, western France, we observed fanning-out and curved series macroscopic ridges on surface a newly formed biofilm. The structure resembles late Ediacaran fossil Arumberia which is globally distributed Australia, Avalonia, Baltica, Siberia India, always confined to intertidal delta-plain settings subject periodic desiccation or fluctuating salinity. Although origin remains enigmatic, wrinkled rugose...
Dickinsonia in the central Urals occurs a succession transitional from marginal marine to non-marine. Even within this sequence appears be restricted least facies interpreted as coastal lagoon surrounded by tidal flats. Another puzzling aspect is complete absence of other Ediacaran taxa that are usually found together with fossil localities. In fact, Sinii Kamen Member Cherny Formation yielded an assemblage macrofossils including aspidellamorph and mawsonitomorph holdfasts, frondomorphs,...
Los ejemplares de Dickinsonia los Urales Centrales se caracterizan por una clara simetría bilateral. Tomando en cuenta las observaciones especímenes australianos, consideramos que la llamada’simetría reflexión deslizamiento’ estos fósiles es un fenómeno tafonómico. El gráfico distribución frecuencias tamaño muestra el predominio individuos juveniles población estudiada Centrales. Asumiendo edad individuo manifiesta su tamaño, existe significativo población. Se pueden prever tres escenarios...
Raman and IR spectroscopy studies on propane were performed at pressures of up to 40 GPa ambient temperatures using the diamond anvil cell technique. Propane undergoes three phase transitions 6.4(5), 14.5(5), 26.5(5) in 7.0(5), 14.0(5), 27.0(5) spectroscopy. The identified splitting modes appearance or disappearance peaks, which clearly corresponded changes frequencies as pressure changed. Our results demonstrate complex high-pressure behavior solid propane.
Abstract Macroscopic fossils as composite molds and casts of Ediacara-type soft-bodied organisms were found in the Dzhezhim Formation Timan Range for first time. Among them, representatives palaeopascichnids, arboreomorphs, chuariomorphids, microbial colonies, trace identified. This finding such a large number various Ediacaran on not only develops our understanding their paleogeographic range but also clarifies age limits deposition Formation, stratigraphic position which Upper Precambrian...
The siliciclastic succession of the Ediacaran Chernyi Kamen Formation in Central Urals Russia contains a rich complex fossils that represent situ benthic populations buried life position. present work reports Beltanelliformis konovalovi sp. nov. found as paleocommunity organisms and studied for their morphology spatial distribution. Unlike type species ( B. brunsae ), new are preserved within fine-grained sandstone beds three-dimensional pancake-like or flattened discoidal single, paired,...
Durante más de cuarenta años, los paleopasciquínidos han representado un grupo enigmático fósiles macroscópicos, caracterizados por diferencias sustanciales en la conservación, lo que no conduce a diagnóstico consistente estos organismos. Los se encuentran distribuidos globalmente las secuencias ediacáricas Plataforma Europa Oriental, Avalonia, China meridional, Siberia y Australia. A luz una nueva perspectiva para reanimar el “Véndico” como serie superior formal del Sistema Ediacárico, son...
Research subject. This article presents new data on carbonate facies of the upperUk subformation, Upper Riphean theSouth Urals. A particular attention is paid to distribution rare-earth elements (REE) and yttrium (Y) in stromatolitic intraclastic limestones calcareous shales (bulk samples their acetic acid leachates). Materials methods . We have studied lithological features geological section thin sections. The contents trace rocks were determined by ICP-MS method at IGG UB RAS...
A theory of abiotic deep petroleum origin explains that hydrocarbon compounds are generated in the upper mantle and migrate through faults into Earth's crust. There they form oil gas deposits any kind rock structural position. Until recently one main obstacles for further development this has been lack reliable reproducible experimental results confirming possibility spontaneous synthesis complex systems at high pressure temperature. Our demonstrate hydrocarbons under conditions is a real...
The macroscopic fossils, an Ediacara-type composite moulds and casts, were found in the Dzhezhim Formation of Timan Range for first time. Among them, representatives palaeopascichnids, frondomorphs, chuariomorph colonies, arumberiamorph structures as well trace fossils diagnosed. Finding a large number various Ediacaran on both develops understanding their palaeogeographic range, also clarifies age limits deposition Formation, whose stratigraphic position Upper Precambrian section was controversial.
El Grupo de Asha los Urales meridionales, inicialmente definido por Albert Olli como complejo sedimentario paleozoico, hace más medio siglo, fue considerado una sección clave para el Véndico (Ediacárico) la vertiente occidental meridionales. Sin embargo, secuencia sedimentaria terrígena unos 1.700 m espesor se caracteriza biodiversidad inusualmente baja macrofósiles ediacaranos, lo que podría explicarse edad relativamente temprana del grupo y posible evento extinción masiva marca final...
