Plate P1. Woody tissues preserved as vitrinite. 2. T5945; Hole 1116A; 102.14 mbsf. Cell contents have been humified and show slightly higher reflectances compared with the cell walls. Some small voids are present within some cell lumens, resulting in the presence of bright internal reflectances. These occurrences are referable to porigelinite. The ICCP (1971) terminology would include the cell contents in collinite, whereas the SAA system would place it within telovitrinite. Small differences are present in reflectance between the cell contents and the cell walls and neither shows distinctive fluorescence, so the fluorescence-mode image is not included (reflected light; field width = 0.22 mm; telovitrinite reflectance = 0.51%-0.46%).
