Figure 1. Biostratigraphic summary of the Leg 175 sites drilled in the Lower Congo Basin (Sites 1075, 1076, and 1077) and Mid-Angola Basin (Sites 1078 and 1079). Open circles = calcareous microfossils (N = calcareous nannofossils); solid circles = siliceous microfossils (R = radiolarians, D = diatoms, and S = silicoflagellates); WD = water depth. Hatched regions indicate the maximum penetration at the sites.
