Quantitative Parameters of Diagenetic Transformations in Eocene–Pleistocene Sediments of the Vøring Plateau (Norwegian Sea) Depending on Their Sedimentation Conditions

Abstract

The degree of intensity of diagenetic transformations was studied using one-dimensional regressive analysis of the distribution of Fe, Mn, and C_org contents, as well as the density of marine sediments along depth in the sections of the studied boreholes drilled on the Vøring Plateau. As a result, we estimated the qualitative parameters of diagenetic processes in the Eocene–Pleistocene sediments. On the basis of one-factor dispersion analysis, we also studied the degree of intensity of diagenetic processes for the main lithological types of sediments of the Vøring Plateau. It is established that, in addition to hiatuses and the influence of bottom currents and turbidites, the degree of diagenetic transformations in the Eocene–Pleistocene depended on the following main factors: sedimentation conditions, lithological composition of sediments, and the amount of organic carbon in composition of the Eocene–Pleistocene sediments of the Vøring Plateau.
