Figure F109. Close-up photograph of an earlier formed anhydrite vein structure (V1-V1b) crosscut by later anhydrite vein with coarse-grained anhydrite as open-space fill (V2). A thinner vein, V2b, branching off the main vein V2 in the upper part of the piece, can be seen (at 32 cm) cutting across another member of the earlier formed vein structure and its siliceous halo (interval 193-1188F-25Z-1 [Piece 5, 30-42 cm]; 295.88 mbsf).
