Fig. 9.9 Fence diagram for seventeen core logs and one outcrop section from across the Kasai
study area. Depth to basement is based on basement intercept depths and the regional surface
topography is used as the baseline for hanging all sections and core logs. The Kasai study area

shows a complex stratigraphic framework with irregular basement topography and seven
distinct stratigraphic units (note only six shown on fence diagram) that can be correlated across
the study area
