Abstract—

The section of Maikop deposits on the Belaya River upstream of the town of Maikop is characteristic of Western and Central Ciscaucasia; it is well exposed and well-studied and can be considered as the type section of the Maikop Group. The section shows a continuous transition from the underlying white marl of the Belaya Glina Formation to dark clay lying at the base of the Maikop Group. The lower Oligocene part of the section exposes an almost uninterrupted outcrop of the Pshekha Formation and shows unconformities at the base and top of the Polbian Bed. These are overlain by the lower non-carbonate and upper carbonate subformations of the Morozkina Balka Formation and the Batalpashinsk and undivided Upper Oligocene Septarian + Zelenchuk formations. This paper contains a detailed lithological description of the section with a summary of its fossils. The composition of the studied microphytoplankton and animal remains, including nannoplankton, planktonic and benthic foraminifers, mollusks, and ichthyofauna is described and paleomagnetic study results are presented. The study of palynology and dinocysts from the same series of samples was previously completed. The history of the study of the Maikop Group and its subdivision into formations are discussed. This paper discusses the possibility of using the data for correlation and reconstruction of the depositional environment.

渐新世部分麦科普镇（西奇考克西亚）上游的贝拉亚河段迈科皮安族的层位表型

摘要—

迈科普镇上游的贝拉亚河上的迈科普矿床部分是西高加索地区和中西洋地区的特征。它是经过充分研究和深入研究的，可以被认为是舞妓集团的类型部分。该部分显示了从Belaya Glina地层下面的白色泥灰岩到位于Maikop组底部的深色粘土的连续过渡。该断层的下渐新统部分露出了不间断的Pshekha组露头，并在Polbian床的底部和顶部显示出不整合面。这些被Morozkina Balka组和Batalpashinsk组的较低的非碳酸盐和较高的碳酸盐亚型和未划分的上渐新世的Septarian + Zelenchuk组所覆盖。本文包含该部分的详细岩性描述及其化石摘要。描述了所研究的微浮游植物和动物遗体的组成，包括纳米浮游生物，浮游和底栖有孔虫，软体动物和鱼科动物，并提出了古磁研究结果。先前已经完成了对来自同一系列样品的孢粉学和藻囊的研究。讨论了Maikop小组的研究历史及其细分形式。本文讨论了将数据用于沉积环境的相关性和重建的可能性。讨论了Maikop小组的研究历史及其细分形式。本文讨论了将数据用于沉积环境的相关性和重建的可能性。讨论了Maikop小组的研究历史及其细分形式。本文讨论了将数据用于沉积环境的相关性和重建的可能性。
