Plate P1. Woody tissues preserved as vitrinite. 3. T5855; Hole 1116A; 102.14 mbsf. Both the cell walls and the contents have been humified. The cells have probably had additional humic matter added. Reflectances of the cell contents are higher than for the cell walls. Cell walls include primary cell walls but are sufficiently thick to indicate that some secondary cell wall material must also be present. In the original ICCP terminology, the walls would be termed telinite and the contents collinite. The SAA terminology would place the whole field within the telovitrinite category. Fluorescence of both the cell contents and walls is low (reflected light; field width = 0.22 mm; telovitrinite reflectance = 0.54% [cell lumens], R = 0.36% [cell walls]).
