Plate P5. Cell walls transitional to suberinite. 1. T5809; Hole 1109D; 387.86 mbsf. Telovitrinite with fluorescing cell walls and a prominent pyrite lens. Some of the fluorescing tissues are similar to those in Plates P3, p.25, and P4, p.26, but some is similar to suberinite (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.31%). 2. T5809; Hole 1109D; 387.86 mbsf. Same as figure 1, but in fluorescence mode. In the upper right of the field the regular stacked structure normally associated with suberinite is present, but in other parts of the field is it lacking, but the cell walls show similar fluorescence properties (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.31%). 3. T5814; Hole 1109D; 551.24 mbsf. Telovitrinite with abundant fluorescing cell walls, some of which are suberinite. The part of the plant that has been preserved is probably part of the periderm, and it appears that multiple periderm layers are present in this wood type. The dark voids are similar in appearance to resinite, but the fluorescence-mode plate shows that resinite is not present and they represent open voids (reflected light; field width = 0.22 mm; mean vitrinite reflectance = 0.39%; suberinite reflectance = 0.18%). 4. T5814; Hole 1109D; 551.24 mbsf. Same as figure 3, but in fluorescence mode. The material most closely referable to suberinite is in the upper right of the field, but this shows weaker fluorescence compared with the cell walls in the center of the field. The structure and fluorescence of some of the layers toward the base of the field are similar to those of cutinite (reflected light; field width = 0.22 mm; vitrinite reflectance = 0.39%, suberinite reflectance = 0.18%).
