摘要

摘要获得了贝洛格罗德尼地层（达尼安期）地层类型的磁性和化学元素组成数据，并对其进行了周期分析。根据岩磁和地球化学参数垂直序列的傅立叶变换，确定了该剖面中与地球轨道长偏心期和短偏心期相对应的周期，并估算了沉积时间（约 2.1 百万年）和釉云母形成率（约 1 厘米/千米）。

Cyclostratigraphic Analysis Results of the Rock Magnetic and Geochemical Characteristics of Belogrodni Formation Stratotype (Danian Stage in the Volga Right Bank Area Near Saratov)

Abstract

Data on the magnetic properties and composition of chemical elements in the stratotype of the Belogrodni Formation (Danian Stage) were obtained and their cyclostratigrapic analysis was carried out. Based on the Fourier transforms of vertical sequences of petromagnetic and geochemical parameters, cycles corresponding to the long and short eccentricity periods of Earth’s orbit were identified in the section and the sedimentation time (~2.1 myr) and glauconite formation rate (~1 cm/kyr) were estimated.
