Plate P6. Suberinite and cutinite. 1. T5843; Hole 1115C; 562.86 mbsf. Telovitrinite and suberinite, with the suberinite showing positive alteration on prolonged irradiation with the fluorescence excitation beam. Vitrinite reflectance = 0.32% prior to alte

Plate P6. Suberinite and cutinite. 2. T5809; Hole 1109D; 387.86 mbsf. Same as figure 1, but in fluorescence mode. Fluorescence from the suberinite is much stronger from the area where alteration has occurred (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.32%).
