Palaeomagnetic Results from Lower Devonian Rocks of the Cheviot Hills, Northern England
Palaeomagnetic work has been undertaken on four different rock types from the Cheviot Hills, Northern England. A total of 64 independently oriented handsamples from 21 different sites have been examined for their remanent magnetization. The rocks have been dated (K/Ar) as Lower Devonian. The most re...

| Summary: | Palaeomagnetic work has been undertaken on four different rock types from the Cheviot Hills, Northern England. A total of 64 independently oriented handsamples from 21 different sites have been examined for their remanent magnetization. The rocks have been dated (K/Ar) as Lower Devonian. The most reliable palaeopole has been obtained from the combined results for the rhyolites and the andesites of the Cheviot volcanic series. It is situated at position 11° S, 140° E (α95= 18°, 11 sites, 35 handsamples, af cleaned). This pole and also some preliminary poles calculated for the metamorphosed andesites and the Cheviot Granite support the existence of a Lower Devonian group of palaeomagnetic north poles in the region of New Guinea as defined by previously published results from other British formations. |
