Description
Biogenerated textures of the granular type. (a) Fractures of different generations cutting the basaltic glass. Note how the degree of bioalteration differs between two fractures. DSDP sample 46-396B, 17R-3, 62-70. (b) Bioalteration at the junction between two fractures. DSDP sample 69-504B, 4-2, 0-20. DSDP sample 418A, 30-3, 4-6. (c) Light photomicrograph showing a thick zone of bioalteration of the granular type between fresh glass and abiotically altered glass. Figures 3a and 3b are BSE-SEM images. Abbreviations are as follows: FG, fresh glass; GT, granular type bioalteration; AB, abiotic alteration
