Where: Bosnia and Herzegovina (43.2° N, 18.5° E: paleocoordinates 42.5° N, 17.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Langhian (16.0 - 13.8 Ma)

• Using the 15.31 ± 0.16 Ma 40Ar/39Ar age for a volcanic ash layer in the upper part of the section as a tie-point, these small-scale cycles are tuned to the ~ 100-kyr cycles of the eccentricity curve. This correlation indicates the investigated sediments accumulated between ~ 15.8 and ~ 15.2 Ma, i.e. during the Early Langhian. The reversed palaeomagnetic polarity of the carbonate-dominated part of the section is correlated to chron C5Br.
