Figure 4From: Microbial and hydrothermal aspects of ferric oxyhydroxides and ferrosic hydroxides: the example of Franklin Seamount, Western Woodlark Basin, Papua New GuineaTEM images of microbial forms in Fe–Si–Mn oxyhydroxides from Franklin Seamount. (a) and (b) Typical fragments of anhedral agglomerates of amorphous iron oxyhydroxides, sample M2202–2A-1 (106920), height of images 2.6 μm. (c) Pseudo? branching filament, sample M2022-3B (106926), height of image 13 μm. (d) Filament exhibiting hollow structure, sample M2192 loc. 1 (106848), height of image 2.6 μm. The walls consist of regular bands of amorphous iron-silica oxyhydroxides. (e) Braided filament, sample M2202-2a-1 (106920), height of images 4 μm. (f) Amorphous iron oxyhydroxides (see arrow) agglomerated on a typical filament, sample M2202-2a-1 (106920), height of images 5 μm.Back to article page
