Plate P6. A. Elongate pores parallel to lamination occurring only in more friable laminae (Sample 201-1229A-11H-1, 31–34 cm; 89.2 mbsf). B. Large centimicron-size dolomite rhombs occur at only 7.5 mbsf at Site 1229. It is distinguished from all other dolomite rhombs by etched corners (Sample 201-1229D-2H-1, 71–72 cm; 7.5 mbsf). C, D. Foraminiferal test filled with fringes of fibrous calcite cement partially replacing the original test. A second generation of decimicron-size, probably dolomitic, blocky cement is filling the central cavity. C. Sample 201-1229A-12H-5, 68–69 cm; 105.1 mbsf. D. Sample 201-1229A-12H-5, 68
