| contents | In order to determine the bulk magnetic impact of all 22 classified IRD lithologies, the specific petromagnetic properties of each were investigated in detail. In order to represent host rock composition as good as possible and to meet the magnetometric sensitivity requirements, the largest available IRD particles (dropstones) of each IRD species were selected, that were typically of granule or pebble size. Where such large particles were not available, several petrologically similar coarse sand-sized particles were combined in one sample. Great care was taken in sample preparation and sample holder correction to reach reliable values even for small and low-magnetic samples. In addition to magnetic properties, we also provide averaged IRD counts of HLs and in ILs for each IRD lithology. |
