Magnetite Plaquettes Barrel-shaped stacks of discs, first noted by Jedwab (1971), make up the third and, perhaps, most distinctive form of magnetite (Fig. 7).

A novel authigenic magnetite source for sedimentary ...

Abstract. We report a novel authigenic nanoscale magnetite source in marine methane seep sediments. The magnetite occurs in large concentrations in multiple horizons in a 230 m sediment core with gas hydrate–bearing intervals. In contrast to typical biogenic magnetite produced by magnetotactic bacteria and dissimilatory iron-reducing bacteria ...

Magnetic properties of iron minerals produced by natural ...

The minerals that form are often characterized by broad particle-size distributions, lack of specific crystal morphologies, variable mineralogy and the inclusion of impurities in the mineral lattice. Among other biogenic phases, important magnetic minerals such as goethite, hematite and magnetite are common products of BIM processes (e.g ...
