The sediments of 'the Koobi- Fora formation in the East Rudolf' basin have yielded a ricu assemblage of'. f'au~a~, hominid f'ossilsand stone artef'actso Paleomagnetism has, over the recent years, become a usef'ul tool in the dating of'the sitas f'rom which these assemblages have been excavated. This thesis outlines how' paleomagnetic polarity - Stratigraphic correlation has been used as a dating tool in this area& The introduction, chapter one, briefly outlines the importance of' the region of study to other earth science subjects, the early paleomagnetic work in the area and the aim of the thesiso The location and geology of'the East Rudolf basin as a whole is described in Chapter two. Chapter three deals with the paleomagnetic sampling techniques a.ndgives a more detailed description of the stratigraphic succession of 'the sedimentary beds in each of'.the three areas sampled in the 1973/4 season. The dIstr-Lbut'Lonof'the sampled horizons is also described. All .the samples collected in the field ,,,e remeasured and cleaned in the laboratory The measurement procedures and the results obtained o.'\e. given chapter six. while the interpretation of the results obtained is outlined in chapter seven.
