Interpretation of Late Precambrian Palaeomagnetic Results from Africa
(University of Nairobi, 1971-12-17)
An apparent polar wander path for the Late Precambrian of Africa is proposed. It is defined by new data from Kenya and Tanzania covering the period 800 My to 1000 or 1100 My, and with an average polar wander rate of about ...
Paleomagnetic Stratigraphy and Chronology of Hominid-bearing Sediments East of Lake Rudolf Kenya
(University of Nairobi, 1974-02-08)
The Palaeomagnetism of the Kisii Series, Western Kenya
(University of Nairobi, 1971-12-17)
The Precambrian Kisii Series in Western Kenya is unmetamorphosed and contains andesites, rhyolites, quartzites and basalts. The basalts, for which a minimum K-Ar age of 930 My is cited, were sampled at 15 sites, and after ...
The Palaeomagnetism of Late Cenozoic Volcanic Rocks from Kenya and Tanzania
(University of Nairobi, 1976-06)
Palaeomagnetic results from 246 sites in the East African Cenozoic volcanics are reported. Palaeomagnetic pole positions are obtained for different age ranges as follows: 0–1.8 My, 104° E, 89° N, A95= 3° (54 sites); 1.8–7.0 ...
The Olduvai event at Olduvai Gorge
(University of Nairobi,, 1976)
Palaeomagnetic polarity measurements from Beds I and II at Olduvai Gorge are described, and used to define the extent of the Olduvai event in the Olduvai Gorge section. The upper boundary of the event occurs very close to ...
An experimental study of palaeosecular variation
(University of Nairobi, 1971-05-17)
A total of 83 selected palaeomagnetic results are used in a latitude analysis of palaeosecular variation to show that Cox's 1970 model for secular variation fits the data, provided the dipole wobble is between 1 1/2° and ...
The recent secular variation of declination and inclination in Kenya
(University of Nairobi, 1975)
Oriented specimens of very young lavas have been collected from 3 volcanic sites in Kenya in order to determine the declination and inclination angles at the times the lavas cooled. TheseD andI values have been tentatively ...
