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.
