Paleomagnetic measurements of discrete samples of sediment core Co1401 from Levinson-Lessing Lake, Siberia

The dataset include the data of 903 discrete samples taken from sediment core Co1401. It comprises the mass and magnetic susceptibility, natural remanent magnetization (NRM), and alternating field (AF) demagnetization of NRM performed at peak fields of 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, and 80 mT. Please note that the core was AF demagnetized using a peakfield of 15 mT before samples were collected.Additionally shown are the anhysteretic remanent magnetization (ARM) imparted imparted by 80 mT peak AF, 100 µT bias field, the AF demagnetization of the ARM at peak fields of 10 mT and 60 mT, and the isothermal remanent magnetization (IRM) imparted at 0.9 T. Measurements were performed at the cryogenic magnetometer laboratory of the Geological Survey of Norway in Trondheim (NGU).
The relative palaeointensity (RPI) is calculated using the partial NRM (pNRM) between the 30 and 50 mT AF step and the magnetic susceptibility, ARM and IRM as normalizers. The charachteristic remanet magnetization (ChRM), RPI and PSV is not given for samples discarded during evaluation. The presented age model results from correlation of RPI(ARM) features to the most recent version of GLOPIS-75. Please note: the RPI age model does not consider possible influences of the lock-in depths.
