Plate P13. Dispersed organic matter. 1. T5842; Hole 1115C; 514.24 mbsf. Leaf preserved in claystone. The leaf no longer contains the tissues within the cuticle (mesophyll tissue). However, these must have been there at the time of deposition, otherwise the two cuticle surfaces would have tended to be torn apart. Subsequent diagenesis has apparently removed these tissues. The amber-colored wisps are probably also derived from leaf tissue (reflected light; field width = 0.22 mm; mean vitrinite reflectance = 0.29%).
