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.

Electron-microprobe analyses (Table 5) were completed on a selection of grains from 11 samples, with a CAMECA SX-50 instrument (University of Louvain-la-Neuve, Belgium), under...

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...

The unit-cell parameters (Table 4) were calculated with the least-squares refinement program LCLSQ 8.4 (Burnham, 1991), from the d-spacings corrected with an internal standard...

The sediment cores were sampled with a resolution of 10 cm, resulting in a total of 290 samples (Table 2). Around 250 mg of dried sediments was mechanically crushed through...

Paleointensity versus age of all the sedimentary sequences of the present study, of the synthetic curve resulting from its compilation from other curves, and of the reference...

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...

Selected intervals of down-core variations of normalised relative paleointensity, ChRM inclination and declination, and the reversal angle. (A) Core CON 01-603-2: numbers in the...

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...

Palaeomagnetism was the method used for dating sediments older than the time span covered by AMS 14C dating. Geomagnetic palaeointensities recorded in Lake Baikal sediments were...

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...

In order to get a complete geochemical signature, 14 P-rich concretions, chosen among the different cores, were acid digested (Table 3a and Table 3b). In a clean laboratory, 1.7...

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

In the figure, the average sedimentation rates are also indicated. The grey bands correspond to the time span of stadial+glacial periods. To the right, the blow-up of the area...

The diatom succession at Academician Ridge is similar to the one from Continent Ridge and the two records, despite having very different sampling resolution, can be easily...

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...

In order to characterise Lake Baikal sedimentary responses to global climatic changes that may be recorded in marine sediments, we compared our paleomagnetically dated...

In order to get a complete geochemical signature, 14 P-rich concretions, chosen among the different cores, were acid digested (Table 3a and Table 3b). In a clean laboratory, 1.7...

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