摘要：

Summary. One hundred and fifty oriented samples were collected from 12 sites from the Tertiary basalts of Wadi Abu Tereifiya (30.0°N, 32.1° E). After alternating field demagnetization the mean direction of the natural remanent magnetization is, D= 187.9°, I= ‐20.8° with α95= 5.8°. This yields a palaeopole at 69.4°N, 188.3° E. Also, 30 oriented samples were collected from two sites from Mandisha in Bahariya Oasis (28.4°N, 28.9° E). After cleaning, the mean direction of the NRM is D= 191.0°, I= 5.2° with α95= 9.9°. This yields a palaeopole position at 58.2°N, 186.7° E. Besides, the NRM of 70 oriented samples collected from seven dioritic dykes from Wadi Abu Shihat (26.3°N, 33.2° E) was found to have a mean direction, D= 142.0°, I= ‐0.3°, which leads to a palaeopole position at, 44.9°N, 273.0° E. This agrees with other Mesozoic pole positions from Africa. Copyright © 1979, Wiley Blackwell. All rights reserved
