Plate P3.
Vitrinite showing fluorescence from cell walls. 4. T5809; Hole
1109D; 387.86 mbsf. Same as figure 3, but in fluorescence mode. Oblique section
of wood preserved as telovitrinite with cell structures outline by fluorescing
cell walls. Some structures are probably present within the cell walls, and some
fluorescence can be seen from the floors of some cells, with the fluorescence
being transmitted through the cell contents (reflected light; field width = 0.22
mm; vitrinite reflectance [cell contents] = 0.34%).
