Integrated Magnetic Susceptibility and Geochemical Record of δ13C Anomalies in the Berriasian and Valanginian Sections from the Tethyan Domain (Western Carpathians, Poland)

Abstract

New magnetic susceptibility (MS), stable isotope, and geochemical (major and trace elements) data are presented from the three Berriasian–Valanginian pelagic sections from the Western Carpathians of Poland. MS correlates well with lithogenic influx and reflects exactly the short-term transgressive–regressive cycles in the interval below the δ13C event (the Weissert event) recorded in the upper Valanginian. The pattern of changes in MS recorded for the Weissert event is more complicated, most probably also reflecting significant climatic changes. Redox-sensitive indicators (Th/U, Ce/Ce*) account for significantly oxygen-depleted conditions combined with relatively low content of productivity indicators (Al-normalized P, Ba, and Cu).
