Ultrafinegrained magnetite in deepsea sediments ...

+

A new extraction technique now permits ultrafine magnetite crystals to be separated from a variety of deepsea sediments. Morphologic characterization of these particles with transmission electron microscopy reveals the presence of several distinct crystal types, some of which closely resemble those formed by the magnetotactic bacteria.
