a succession of Badenian (Langhian, Middle Miocene)

sediments at the type locality of the Badenian, the old brickyard Baden-Sooss in the Vienna Basin. The sedimen-tary succession of the 102-m-cored interval consists of more than 95 % bioturbated, medium-to-dark gray marly shales with carbonate contents between 11 and 25 % and organic carbon contents between 0.35 and 0.65%. Biostratigraphic investigations on foraminifera (mainly lower part of Upper Lagenid Zone) and calcareous nannoplankton (standard zone NN5) indicate an early Badenian (Langhian) age. Cycles in carbonate content, organic carbon content, and magnetic susceptibility have been identified by power spectra analysis. Correlations between the three variables are extremely significant. Using cross-correlation, periods around 40 m correlate significantly with the 100 kyr-1 eccentricity cycle, the *20 m periods with the obliquity cycle, and the 15 to 11-m periods with both precession cycles. Wavelet transformation and decomposition of composite periodic functions were used to obtain the posi-tion of the cycle peaks in the profile. Cross-correlation with orbital cycles (La2004) dates the Baden-Sooss core between-14.379 ± 1 and-14.142 my ± 9 kyr
