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%).
