Summary: Remanent magnetic properties were measured in basalt from sites 279 (Hole 279A), 280 (Hole 280A), 282 and 283. Unusually low intensities of remanence were measured in Hole 280A specimens. At sites 279 (Hole 279A) and 283 the remanent magnetization was less important than the induced magnetization. Thermomagnetic analysis indicated that the basalt was of deuteric oxidation class I, with titanomagnetite or titanomaghemite as the magnetic mineral. The Site 282 basalt was drilled in a quiet zone; viscous remanent magnetization (VRM) experiments showed that this quiet zone cannot be caused by VRM of the oceanic crust. However, very unstable magnetic properties of Site 283 basalt allowed it to acquire VRM very readily.
