Figure F31. DEBI-pt scanning image of subsample of Sample 336-U1382A-10R-3-MBIOD. A. Visible image showing broken plagioclase-olivine-phyric fine-grained basalt. Clay and Fe oxyhydroxides partially replace olivine grains and fill vugs. B. Fluorescence image showing the presence of altered material (maroon) and bacteria (green). The bacteria are heterogeneously distributed and are localized to the iron oxides. They appear to be concentrated in the lowermost part of the rock, which features a crack and is noticeably vuggy. Scale bar = 10 mm.
