Fig. 2: Overview of collected sediment cores and calculated sedimentation rates.

From: Volcanic evolution of an ultraslow-spreading ridge

Fig. 2

The collected sediment cores are marked as stars on a 70 m resolution bathymetry with 2 times vertical exaggeration. Yellow stars are cores that have been dated and white stars are cores that are photo-scanned and analysed using X-ray fluorescence element scanning. Their chemo stratigraphy has been correlated with the dated cores to strengthen the age model (details in Supplementary Information). The outline of the axial volcanic ridges (AVRs) is marked with a red dashed line and numbered according to their location along the Mohns Ridge. Inset in the upper left corner shows the sedimentation rate for each of the dated cores, with a number corresponding to the location on the map (see Table S1 in the Supplementary Information). The average sedimentation rate is estimated to be 6 cm/Kyr for the entire rift valley.
