Fig. 2: Stratigraphic correlation between the Albjära-1, Fågeltofta-2 and Billegrav-2 cores based on detrended Al and S signals, 405-kyr filtered outputs and molybdenum profiles.

A 12-point (corresponding to 12 mm) smoothed Al series was used in the cyclostratigraphic analysis, but the Al and S series of the Albjära-1 core in this figure is smoothed with a window of 150 mm to visually emphasize the cycles. Mo curves from the three cores have the same smoothing window of 60 mm to visually correlate every 405-kyr cycle. All results shown for the Fågeltofta-2 and Billegrav-2 cores are from ref. ²⁷ except for the additional Al cycle column in the Agnostus pisiformis Zone of the Billegrav-2 core. The Ap-1a and Ap-1b cycles refer to one Ap-1 cycle in ref. ²⁷. The boundary between the Agnostus pisiformis and Lejopyge laevigata zones in the Billegrav-2 core was adjusted to ~117.3 m based on Mo correlations. The base of Stage 10 defined as in Fig. 1.
