Figure 5From: Chromite oxidation by manganese oxides in subseafloor basalts and the presence of putative fossilized microorganismsOptical microphotographs showing the filamentous structures in the rhodochrosite. (A) shows the abundance of filamentous structures in a rhodochrosite filled phenocryst. (B) Close up of filamentous structures showing their smooth, curvi-linear appearance. (C) microphotograph showing a filamentous structure coiled more than 360°. (D) microphotograph showing the twisted, spiral appearance. (E) microphotograph showing branching. Scale bar: (A) 100 μm, (B) 50 μm, (C) 5 μm, (D) 10 μm, (E) 10 μm.Back to article page
