Summary: Samples from DSDP Leg 73 cores at sites 519, 521, 522 and 523 contain fossil bacterial magnetite, found to be the main carrier of the natural remanent magnetization in Eocene-Quaternary sediments. Most types of bacterial magnetosomes occur in chains of identical particles mostly falling in the theoretically determined size range of single-domain magnetite. The bacterial magnetite is illustrated by SEM.
