Figure F115. Photomicrographs of mineral particles from Hole 1188A showing bacterial habitation. Ground samples (<100 µm; Sample 193-1188A-5R-1, 17-21 cm; 33.77 mbsf) of translucent fragments of dacitic volcanic glass with (A, B) plagioclase microlites (arrows) and microcrystalline domains with (C, D) spheroidal crystallites (arrows) are shown. DAPI-stained bacteria are located on the surface, flat planes, and edges of these fractures.
