Response of foraminiferal assemblages to precession-paced environmental variation in a mid-latitude seaway: Late Turonian greenhouse of Central Europe

Foraminiferal assemblages were studied as part of a multi-proxy dataset from an expanded record of Late Turonian hemipelagic deposition obtained from the Bch-1 research borehole in the Bohemian Cretaceous Basin (Central Europe). Based on fluctuations in the Si/Al ratio, precession-paced cyclicity (18–23 kyr) is recognized in the studied interval and interpreted to reflect changes in seasonality. This study focuses on relationships between the astronomically controlled lithological cyclicity and the composition of foraminifera assemblages, together with variation in other parameters (geochemical, geophysical, palynological) that may provide further information about palaeoenvironmental change on a precession time scale.
