| Zusammenfassung |
| A multiproxy ($\delta$$^{18}$O, $\delta$$^{13}$C, magnetic susceptibility, gamma-ray spectroscopy) stratigraphy was developed from a 31.2-m-thick Upper Valanginian to lowermost Hauterivian section of the Bersek Marl Formation in Gerecse Mountains, Hungary, comprising alternating marlstone layers of varying clay and carbonate content. The aims of the study were to understand the mode of sedimentation in the Gerecse subbasin and establish a reliable correlation with other Cretaceous sections using the isotopic signature of the Weissert Event.\newline
In the studied section, the bulk carbonate $\delta$$^{13}$C signal shows sustained, elevated values (up to 2.7\permil\) up to 19.2 |
