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 ...
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 ...
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 ...
