In the Black Sea Region, 13 sections for carbonate platform (Pontides Platform) were selected to provide a more detailed foraminiferal biostratigraphy, and strontium isotope and trace elements (geomarkers) analysis for the purpose of this study. This is to give the shallow benthic fauna, its extinction and survival on the Cretaceous and Tertiary Boundary (KT Boundary), Pontides Platform, and the shallow shelf environment. In Devrekani section, where the fossils of algae, bryozonans, foraminifers, rudists and corals of the Upper Cretaceous (Maastrichtian) and Danian-Thanetian age occur in the thickness of 32 m. The most frequent marker foraminifers are Siderolites calcitrapoides, Hellenocyclina beotica, Orbitoides medius, O.apiculatus, Ompalocyclus macroporus, Cideina soererii, Simplorbites gensacicus, Smoutina cruysi, Navarella joaguini, and Daviesina sp. These forms increases towards the KT Boundary. According to rock textures, limestone and marl vary from packstone to biomicrite of w … More ackestone, after the basal sandstone. The KT Boundary showed the beds between samples 806 and 807. In the following strata, the most frequents are bryozoan and echinoids, then small benthic foraminifers of Rotaliidae, Miliolidae, Texturariidae, and well known Planorbulina cretae and Laffiteina. By texture, it is biomicrite with an increased amount of organic matter. In Cide section, the Upper Cretaceous and Paleocene beds are about 145m thick, and are examined along the road with samples 901 and 939. The KT Boundary showed the beds between samples 929 and 930. The Maastrichtian pelagic foraminifers below the KT Boundary belong to Gansserina gansseri-Abathomphalus mayaroensis Zones.Extinction of biota is accompanied by peak of strontium isotope value in Devrekani section, and by peak of concentration of elements as Cr, Co, Ni, and Zn, except Cu, in Golpazai, respectively. The sedimentation took place in the shallow shelf environment in lagoon to shallow marine (restricted shelf), where it did not essentially changed after the KT Boundary. Less

在黑海地区，选取了碳酸盐台地(蓬蒂斯台地)的13个剖面，以提供更详细的有孔虫生物地层学、锶同位素和微量元素(地质标志物)分析。这是为了给出浅水底栖动物及其在白垩纪和第三系边界(KT边界)、庞迪德台地和浅海陆架环境中的灭绝和生存。在Devrekani剖面，发现了上白垩统(Maastrahtian)和达尼亚-塔尼期(Danian-Thanetian)的藻类、苔藓动物、有孔虫、有孔虫和珊瑚等化石，最常见的标志性有孔虫有钙化铁线虫、环状有孔虫、中间有孔虫、针叶藻、大孔虫、大豆有孔虫、gensacicus、Smoutina Cruysi、Navarella joaguini和Daviesina sp.这些形式随着KT边界的增加而增加。根据岩石结构的不同，w…的包岩不同，灰岩和泥灰岩也不同。更多的是泥岩，之后是底部的砂岩。KT边界显示了样品806和807之间的层。在下面的地层中，最常见的是苔藓动物和棘形动物，其次是小型底栖有孔虫，如轮虫科、线虫科、织纹虫科，以及众所周知的Cretae和Laffiteina。从结构上看，它是含有更多有机质的生物硅酸盐。慈德剖面上白垩统和古新统厚度约145m，沿途取材901和939。KT边界显示了样品929和930之间的层位。KT界线以下的马氏远洋有孔虫属于Gansserina gansseri-Abaomphalus mayaroens带，生物群的灭绝分别伴随着Devrekani剖面的锶同位素峰值和Golpazai中除铜以外的铬、钴、镍、锌等元素的浓度峰值。沉积发生在泻湖-浅海(限制陆架)的浅海陆架环境中，在KT界线之后没有发生本质的变化。较少
