Abstract: | Summary Unfortunately most of the cores taken from Salisbury Channel, Lake Victoria which contained discrete pieces of wood suitable
for14C dating were organic-rich and therefore showed a considerable scattering of the remanent magnetic direction plots resulting
in poorly defined oscillations. However, the cores from Pilkington Bay as well as core C5 from Salisbury Channel, Lake Victoria
and the cores from Lake Albert show well-defined paleodeclination and paleoinclination logs. Several cores from Pilkington
Bay and Lake Albert with some14C control can be used to verify the isochronous correlation of the paleodeclination and paleoinclination oscillations. Core
C5, from Salisbury Channel, Lake Victoria, which did not contain any discrete pieces of plant or shell material has been dated
by correlation with other cores which had14C control. This core which shows the best-defined paleodeclination and paleoinclination logs of this study would appear to
have bottomed in sediments in excess of 6000 years BP age and with the work of Maley et al. (1990) from the Cameroons provides
a complete record of the Holocene for Central Africa. |
