Abstract—

New complex data have been obtained for two sections of the Santonian–Campanian boundary of Southwestern Crimea. Article 1 presents detailed geological descriptions of sections, lithological, mineralogical, and paleoichnological materials, and the results of determining macro- (crinoids, ammonoids, belemnites) and micropaleontological (dinocysts, nannoplankton, benthic and planktonic foraminifers) remains. On the basis of the results of research, sea level fluctuations, variations in the activity of allogenic input (including pyroclastic material), and other features of sedimentation have been reconstructed. All macro- and micropaleontological data confirm the late Santonian–early Campanian age of the rocks; for each of the micropaleontological groups, biostratigraphic units have been established and a detailed division of the sections has been carried out.

Kudrino 和 Aksu-Dere 剖面（西南克里米亚）Santonian-Campanian 边界的新生物、化学和磁性地层学：Campanian 下边界层型的全球相关性和选择问题。1. 地质框架、沉积学、生物地层学

摘要-

已经获得了克里米亚西南部桑托尼亚-坎帕尼亚边界的两个部分的新复杂数据。第 1 条提供了剖面、岩性、矿物学和古生物材料的详细地质描述，以及确定宏观（海百合、菊石、箭石）和微古生物（甲壳虫、微浮游生物、底栖和浮游有孔虫）遗骸的结果。在研究结果的基础上，重建了海平面波动、同种异体输入（包括火山碎屑物质）活动的变化以及其他沉积特征。所有宏观和微观古生物学数据都证实了岩石的桑托阶晚期 - 坎帕阶早期；对于每个微古生物群，
