Abstract:
Paleomagnetic results derived from sixteen Black Sea sediment cores. The natural remanent magnetization (NRM) and the anhysteretic remanent magnetization (ARM) were measured with a 2G Enterprises 755 SRM (cryogenic) long-core magnetometer equipped with a sample holder for eight discrete samples at a separation of 20 cm. The magnetometer's in-line tri-axial alternating field (AF) demagnetizer was used to demagnetize the NRM and ARM of the samples. The NRM was measured after application of AF peak amplitudes of 0, 5, 10, 15, 20, 30, 40, 50, 65, 80, and 100 mT. Directions of the characteristic remanent magnetization (ChRM) were determined by principle component analysis (PCA) according to Kirschvink (1980). The error range of the ChRM is given as the maximum angular deviation (MAD). The ARM was imparted along the samples' z-axis with a static field of 0.05 mT and an AF field of 100 mT. Demagnetization then was performed in steps of 0, 10, 20, 30, 40, 50, 65, and 80 mT. The median destructive field of the ARM (MDFARM) was determined to estimate the coercivity of the sediments. The slope of NRM versus ARM of common demagnetization steps was used to determine the relative paleointensity (rPI). In most cases, demagnetization steps from 20 to 65 mT were used to determine the rPI.
Note, in all studied Black Sea sediment cores, samples with SIRM/κ~LF~ ratios >10 kAm^-1^ (SIRM: saturated iso-thermal remanent magnetization, κ~LF~: low-field magnetic susceptibility), empirically found to indicate the presence of diagenetically formed greigite, were omitted for paleomagnetic studies.
