In selected intervals, we measured titanium and iron contents in parallel to rock magnetic parameters (Fig. 9). Titanium content is a good reflection of detrital input since...

Hysteresis measurements of a greigite dominated clay -rich layer with single-domain behaviour hysteresis loop for VER98-1-1.

In interglacial sediments, the magnetic assemblages depict changes in the sedimentation rate, which are traced using the ratio of magnetite over hematite (S-ratio). At the...

Opal content was obtained by measuring the NaCO3 leached solution by inductive coupled plasma with an optical emission spectrometer (ICP-OES). The clay-rich layers are...

Increased presence of greigite (high SIRM/κLF) coincides with maximum sulphur contents observed at the beginning of interglacial stages (Fig. 11A). At similar levels in another...

Higher abundance of greigite during glacial intervals coincides with small increases of the S content (Fig. 11B). Greigite levels in glacial sediments cannot be correlated...

The water content was determined from samples retrieved with cylindrical syringe samplers, weighed wet and weighed again after freeze-drying. The clay-rich layers are...

High temperature measurements of magnetic susceptibility in clay-rich layers. Magnetite, characterised by a Curie temperature of 590 °C, dominates the signal.

The water content was determined from samples retrieved with cylindrical syringe samplers, weighed wet and weighed again after freeze-drying. The clay-rich layers are...

Hysteresis measurements of a hematite dominated diatomaceous layer with pseudosingle to multidomain behaviour of the hysteresis loop for VER98-1-1.

Downcore variations of rock magnetic parameters and simplified lithological description for the sedimentary sequence VER 98-1-14. Here, MIS are denoted by numbers in the...

Hysteresis measurements of a magnetite dominated clay-rich layer with pseudosingle-domain behaviour of the hysteresis loop for VER98-1-1.

Total organic carbon (TOC) and total sulphur (TS) were determined using a LECO CS-225-Analyser. The clay-rich layers are characterised by low levels of TOC and TS. The...

Increased presence of greigite (high SIRM/κLF) coincides with maximum sulphur contents observed at the beginning of interglacial stages (Fig. 11A). At similar levels in another...

Greigite levels in glacial sediments cannot be correlated between cores (Fig. 12), which suggests that greigite concentrations are driven by local processes. We suggest that...

No significant HIRM change is observed at the transition between oxidising and reducing conditions in the sediment (Fig. 9A). This implies that HIRM is not affected by redox...

It shows a loss of a part of the signal at temperatures between 350 and 400 °C, typical disintegration temperatures for greigite. The remaining signal disappears above a...

Anhysteretic remanent magnetisation (ARM) measurements, free of the effect of the dia-, para- and superparamagnetic components, provide an estimation of the magnetic remanence...

Higher abundance of greigite during glacial intervals also coincides with small increases of the S content (Fig. 11B). Greigite levels in glacial sediments cannot be correlated...
