Plate P12. Dispersed organic matter. 1. T5842; Hole 1115C; 514.24 mbsf. Claystone with abundant plant fragments (DOM). In this field most appear to have affinities with liptinite but a few show strong fluorescence (reflected light; field width = 0.22 mm; vitrinite reflectance = 0.30%). 2. T5842; Hole 1115C; 514.24 mbsf. Same as figure 1, but in fluorescence mode. Claystone with abundant plant fragments (DOM). In fluorescence mode the DOM can be seen to be cutinite, but fluorescence ranges from very weak (two longer occurrences) to moderate, short fragments (upper right) (reflected light; field width = 0.22 mm; vitrinite reflectance = 0.30%). 3. T5842; Hole 1115C; 514.24 mbsf. Claystone with abundant DOM. The lower lens is vitrinite, probably telovitrinite, but the upper fragments are mainly of cutinite. These have a very low reflectance and are partially translucent. The organic matter is associated with pyrite (reflected light; field width = 0.22 mm; vitrinite reflectance = 0.30%). 4. T5856; Hole 1116A; 110.93 mbsf. Same as figure 3, but in fluorescence mode. Some structures within the vitrinite may show weak fluorescence, but the cutinite either shows very weak fluorescence or none. It is possible that the small amount of light from the cutinite represents show-through from underlying mineral fluorescence, but the morphology of the phytoclasts is clearly that of cutinite (reflected light; field width = 0.22 mm; telovitrinite reflectance = 0.42%).
