Plate P2. Wood tissues preserved as vitrinite, variable textures, and reflectance. 3. T5817; Hole 1109D; 688.21 mbsf. Woody tissue of varying original composition preserved as vitrinite. Cell walls and cell content are both preserved and both show variations in reflectance, but most of the variation is within the cell contents. The variations are present within a single wood fragment and probably relate in large part to wood composition, but these may have been additionally affected by processes active during early diagenesis (reflected light; field width = 0.22 mm; vitrinite reflectance [cell contents] = 0.54%-0.24%).
