Abstract

Details of the Early-Middle Frasnian boundary interval of the Pymvashor River section (Timan-Pechora Basin, Cis-Urals, in the far north of European Russia) are revealed by biostratigraphically constrained carbonate (δ 13 C carb ) and organic carbon (δ 13 C org ) stable data. The studied interval corresponds to the lower part of the Domanik Formation, which consists of interbedded limestone and shale beds. Organic-rich black shale that lacks bioturbation and benthic organisms indicates an oxygen-depleted depositional environment. Detection of isorenieratene derivatives in organic matter indicates that anoxia was present in the photic zone during deposition. The Pymvashor River section contains δ 13 C carb  and δ 13 C org  isotope records related to the Early-Middle Frasnian isotope Event. The similarity between the Cis-Uralian (this study) and the Chinese δ 13 C carb  and δ 13 C org  oscillations, including the twostep pattern of the recorded major positive excursions, suggests a robust correlation of the Late Devonian Early- Middle Frasnian isotope Event and minor intra-event excursions. Magnitude of variations and values of δ 13 C org  and δ 13 C carb  in the punctata Zone in the Pymvashor River section are minor than those observed in the North American, Polish, and Chinese successions. Such difference may reflect specific variation of the local environments.

俄罗斯北西山-乌拉尔山皮姆瓦肖尔河段切尔内雪夫隆起段Timan-Pechora盆地早-中弗拉斯世(晚泥盆世)碳同位素事件
Pymvashor河段(Timan-Pechora盆地,Cis-Urals,位于俄罗斯欧洲北部)早-中Frasnian边界层段的详细信息通过生物地层学约束的碳酸盐岩(δ13C-carb)和有机碳(δ13C-org)稳定数据揭示。所研究的层段对应于Domanik组的下部,该组由石灰岩和页岩夹层组成。缺乏生物扰动和底栖生物的富含有机物的黑色页岩表明沉积环境缺氧。有机物中异renieratene衍生物的检测表明,在沉积过程中,光区存在缺氧。Pymvashor河段包含与早-中Frasnian同位素事件有关的δ13C碳和δ13C有机同位素记录。Cis Uralian(本研究)与中国δ13C carb和δ13C org振荡之间的相似性,包括记录的主要正偏移的两步模式,表明晚泥盆纪-早-中Frasnian同位素事件与小的事件内偏移之间存在强大的相关性。Pymvashor河段punctata带δ13C org和δ13C carb的变化幅度和值小于北美、波兰和中国序列中观察到的变化幅度。这种差异可能反映了当地环境的具体变化。
