ABSTRACT
For the pollen analytical study of plio-pleistocene history of the Lake Turkana region 30 recent surface soil samples and 34 samples from the surface of the lake deposits have been analysed. It appears that the pollen of the montane forest is not dispersed far by wind, while river transport is more effective.
Using this data the following climatic succession can be inferred from 17 fossil pollen spectra:
from 2.7–2.1 MY: climate warm and humid.
from 2.1–1.8 MY: climate dry with a tendency towards cooling.
from 1.8–1.5 MY: climate more humid and still cooler.
Holocene pollen spectra cannot yet be explained in terms of climate.
