| Abstract: | Peatlands act as information traps; archives reflecting changes in climate and
environment, through pollen assemblages, sediment facies, plant fibre and C14 dating.
The investigation of Maputaland peatlands presents an ideal opportunity to understand
these changes during the Late Pleistocene and Holocene. The Maputaland peatlands in
South Africa could be geographically divided into two distribution areas based on
age: The Holocene age peatlands northwards of the Mkuze River inflow into Lake St.
Lucia and the Late Pleistocene age peatlands south of this inflow. The grouping of
peat thicknesses versus peat ages in a scatter diagram indicates distribution deviations
from the ideal accumulation line. These might represent periods of low or negative
growth and periods of positive or high rates of peat accumulation linked to changing
climatic and ecological environments during the development of these peatlands.
Erosional and depositional events appear to be closely related to local sea-level
fluctuations during the Holocene. Periods of optimum peat accumulation correspond
with Holocene sea-level maxima. |
