Magnetic susceptibility borehole logging of MeBo sediment core GeoB23702-5

DOI

Logging was performed with the sea floor drill rig MARUM-MeBo70 in a borehole drilled with a 103 mm diameter bit. The 1188 Slimhole Memory Magnetic Susceptibility instrument developed by ANTARES Datasystems GmbH was used. Three coils are used for measuring the apparent magnetic susceptibility with an alternating magnetic field tuned to resonate at 1 kHz. The accuracy is within 5 %. The vertical resolution is about 20 cm. The probe was deployed in the memory mode with the logging string being inserted into the drill string and the sensors located below the drill bit. The measurement was conducted as upcast while the drill string was pulled back to the seafloor out of the borehole. The trip out speed was about 1 cm/s and the logging frequency was 0.5 Hz. Data Processing was conducted using the Antares software GeoBase 6.22.1
