• Lithologies from the surface to the middle part of core TDP28/4

•(9.27 m) are composed of dark yellow brown, weathered, silty claystones,

•with intervals of yellow brown, well-lithified, massive, bioclastic

•grainstones (Figs. 4 and 5a). These grainstones were cored

•just below the surface of a disused road bed and present sharp, angular

•contacts with the surrounding lithologies (Fig. 5a), which indicate

•mechanical and not depositional surfaces. Also, this interval is

•not older than Eocene (Section 4.2.2), whereas all recovered sediments

•underlying core TDP28/4 belong to the Campanian (Fig. 4).

•Thus, we consider the top portion of this site to represent an allochthonous

•block (Fig. 4) related to either road rubble or to a large

•slump system off the west side of Kitulo Hill (Pearson et al., 2004).

•From 11 m (core TDP28/5) to the bottom of the hole, the main

•lithologies are olive gray to olive black siltstones and silty

•claystones (Figs. 4 and 5b). Fine lamination is commonly observed

•throughout the hole, but especially from cores TDP28/5–11

•(11–29 m). Calcite vein fractures (cores TDP28/6 and 19), cm- to

•mm-sized, fine sand nodules (core TDP28/17), small bioturbation

•burrows (cores TDP28/15, 29, 38 and 41) and shell debris (e.g.,

•inoceramids) (cores TDP28/15, 16, 18, 22, 24 and 40) are occasionally

•visible. Light gray, sandy partings are relatively frequent in the

•middle and lower part of the hole (50.88–90.50 m) (Figs. 4 and 5b).
