Palaeomagnetic results from late Archaean and early proterozoic granites from South Western Kenya
(Department of Physics, University of Nairobi, 1989)Results of a palaeomagnetic study carried out on the Migori granites exposed in the South Western part of Kenya are presented. The granites of Post-Nyanzian and Post-Kavirondian ages are dated at View the MathML source, ... -
Palaeomagnetic Studies Of The Kapiti Phonolite Of Kenya
(University of NairobiDepartment of Physics, 1972)Specimens of Kapiti phonolite from sixteen sites were treated in an alternating field up to 900 Oe peak. Four sites were discarded on the basis of Watson's Criterion for randomness. Variations in various magnetic parameters ... -
A palaeomagnetic study of lower Proterozoic granites from Western Kenya
(Department of Physics, University of Nairobi, 1979)This paper reports a palaeomagnetic study of the lower Proterozoic granites, exposed in the western part of Kenya and dated at 2530 ± 50 Ma (λRb= 1.39 × 10−11 yr−1). Ten sites out of 13 have yielded stable palaeomagnetic ... -
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 Palaeomagnetism of some Scottish Tertiary Dykes and their Baked Contacts
(University of Nairobi, 1964)This paper presents results of measurements of the directions of magnetization of dyke samples and the associated baked sediments collected from Ayrshire in Scotland. The results suggest that these reversely and normally ... -
Palaeomagnetism of the Cenozoic Volcanic Rocks from East Africa
(University of Nairobi, 1976-01-20) -
The palaeomagnetism of the Ethiopian flood basalt succession near Addis Ababa
(University of Nairobi, 1970-01-22)Measurements on samples from 20 sites in the Ethiopian flood basalt succession yield a palaeomagnetic pole at 80.8° N, 167.7° E with a circle of confidence of 4.3°. The pole for these rocks is significantly different from ... -
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 ... -
Palaeomagnetism of the tororo ring complex, S.E. Uganda
(University of Nairobi, 1973)Palaeomagnetic measurements on the pre-Miocene carbonatite volcanics of Tororo, S.E. Uganda, have yielded a pole at 75.8°N, 195.5°E with A95 = 9.4°. Along with the Tertiary poles from East African rift systems, the ... -
The Paleoecology and Paleogeographic context of Lemudongo locality 1, a late Miocene terrestrial fossil site in southern Kenya
(Department of Geology, University of Nairobi, 2007)The Lemudongo Formation in the Narok District of Kenya comprises a 135-mthick series of predominantly lacustrine and lake basin margin sedimentary rocks with interstratified primary and reworked tuffs. The formation, ... -
Paleomagnetic of the Still Water Complex , Beartooth Mountains, Montana, U.S.A.,
(University of Nairobi,Department of Physics, 1983) -
Paleomagnetic results from the Narosura and Magadi volcanics of Kenya
(Department of Physics, University of Nairobi, 1979)Results of a paleomagnetic study carried out on the exposed volcanic rocks on the western side of the South Kenya Rift Valley are presented. Nine stratigraphic groups ranging in age from Miocene to Pleistocene were sampled. ... -

The paleomagnetism of the Turkana lavas
(University of Nairobi, 1966-02)Directions of magnetizations obtained after cleaning the Miocene lavas from northwest Kenya are presented. The pole position thus obtained, together with similar data from eastern Africa, indicates that no significant ... -
