Figure 7. Two stages of vegetation dynamics, sea level change, and
depositional settings observed in Figures 3-5 modified into the
landscape evolution of the Niger Delta during the Late Quaternary (last
20 ka).
Table 1: Sedimentation rate records of the GCs. Sedimentation rate (SR,
cm/kyr) is the thickness of sediment (Z, cm) that accumulates over a
specified time interval (age difference) (T, kyr). Therefore, SR = Z/T
where = Intervals between samples (cm); T= Age difference between
samples (kyr). The first two intervals (i.e, from 11.7-8.5 + 6.5) ka
were added to compute the SR result for the phase II.
