Abstract

Geochemical studies of Sarmatian clay and siltstone of the Kerch Strait and Taman Peninsula were carried out for the first time in order to identify the paleogeographic features of sedimentation. Based on the results of the interpretation of the geochemical data, the curves of paleosalinity and paleobathymetry of the Yenikale Strait in the eastern part of the Paratethys Ocean were determined. Two regressive (Early Sarmatian; from the middle of the Late Sarmatian) and two transgressive (Middle and the beginning of the Late Sarmatian; the end of the Late Sarmatian–early Meotian) stages were distinguished in the evolution of the studied area. The data on salinity (in ppm) were obtained. The effectiveness of the applied methodology for interpretation of geochemical data in paleogeographic reconstructions, which subsequently can be successfully applied to deposits that lack fossil remains or are characterized by a poor indicator function of the fauna and flora species, has been confirmed.

重建萨玛提亚东部Paratethys的叶尼卡莱海峡古古迹度和古生物测量学：来自地球化学数据的证据

摘要

为了确定沉积的古地理特征，首次对刻赤海峡和塔曼半岛的萨尔马斯蒂粘土和粉砂岩进行了地球化学研究。根据对地球化学数据的解释结果，确定了帕拉提斯海东部叶尼卡莱海峡的古碱度曲线和古生物学。在研究区域的演化过程中，区分了两个渐进阶段（早期的萨尔马蒂安；从晚期萨尔马蒂中期开始）和两个海侵阶段（中期和晚期萨尔马蒂扬开始；晚期萨尔马蒂时期-早梅奥期末）。获得关于盐度的数据（以ppm为单位）。应用方法论解释古地理重建中地球化学数据的有效性，
