Abstract

TheKugarchi Section in the Zilair Synclinorium in the SouthUrals (Russia, Bashkortostan) is one of themost complete sections of the Bukharcha Formation, including the entire Serpukhovian and the lower Bashkirian. This is the type section of the Bogdanovkian Regional Infrasubstage ('Horizon'), the lowermost Bashkirian of the Urals. The section spans the Visean-Serpukhovian andMid-Carboniferous boundaries and contains various ammonoids, conodonts, and foraminifers, providing a good basis for the regional stratigraphy and global correlations. The section has been measured and logged, and its microfacies and fossils are identified in this study. http://dx.doi.org/10.29041/strat.14.1-4.319-347

俄罗斯南乌拉尔Kugarchi剖面Serpukhovian和Bashkirian阶段的牙形刺、菊石、有孔虫和沉积环境

南拉尔(俄罗斯，巴什科尔托斯坦)的Zilair向斜中的kugarchi剖面是Bukharcha组最完整的剖面之一，包括整个Serpukhovian和下Bashkirian。这是波格丹诺夫地区下层(“地平线”)的类型剖面，它是乌拉尔地区最底层的巴什基利亚地层。该剖面跨越visian - serpukhovian和中石炭世界线，含有各种菊石、牙形刺和有孔虫，为区域地层学和全球对比提供了良好的基础。本研究对该剖面进行了测量和测井，并对其微相和化石进行了识别。http://dx.doi.org/10.29041/strat.14.1-4.319-347
