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%).
