Plate P5. A. Diatom frustule more strongly edged than surrounding diatom frustules. Dolomite rhombs growing inside the pores show the same crystallographic orientation (Sample 201-1228A-5H-1, 5–10 cm; 33.45 mbsf). B, C. Replication of diatom frustules on surrounding dolomite (Sample 201-1228A-6H-6, 62–70 cm; 51.2 mbsf). D. Framboidal pyrite growing in the pore space of a diatom frustule (Sample 201-1228A-6H-6, 62–70 cm; 51.2 mbsf).
