Plate P3. Vitrinite showing fluorescence from cell walls. 1. T5809; Hole 1109D; 387.86 mbsf. Longitudinal section of wood preserved as telovitrinite. The cell lumens are mostly filled with humic material, but the degree of compressions is small and some parts of the lumens are open. Cell walls are much lower in reflectance and are strongly fluorescing. Their reflectances are within the range normally associated with liptinite, but they do not represent suberinite. Reflectances of the cell walls are lower in the lower part of the field, but the cell contents have relatively consistent reflectances across the various tissue types (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.37%, [cell walls] = 0.12%). 2. T5809; Hole 1109D; 387.86 mbsf. Same as figure 1, but in fluorescence mode. Longitudinal section of wood with the cells outlined by the fluorescence of the cell walls. The structures present are probably xylem, seen in longitudinal section, with some medullary ray tissues in the upper part of the field. Fluorescence of the cell walls is similar to that for suberinite, but the form of the cells shows that this material is not from cork cells and cannot strictly be referred to the maceral suberinite (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.37%, [cell walls] = 0.12%). 3. T5809; Hole 1109D; 387.86 mbsf. Oblique section of wood preserved as telovitrinite. The cell lumens are partially filled with humic material, but open lumens are still present and little compaction has occurred. Cell walls are much lower in reflectance and are most easily seen in fluorescence mode. The vertical cells represent a medullary ray structure (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.34%). 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%).
