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 alteration and 0.26% after 2 hr of irradiation. The left side of the field was not irradiated (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.32%).
