Palaeomagnetic Studies in the British Caledonides-III Igneous Rocks of the Northern Lake District, England

Palaeomagnetic results are reported from the ‘northern’ Borrowdale Volcanics and from the Carrock Fell intrusive complex. The mean stable remanence direction in the volcanics is D = 0°, I = −46° (α95 = 6°) from 27 sites after allowing for tectonic dip. This result is supported by a decisive fold test in which precision improves by at least a factor of 3. The Carrock Fell Gabbro complex carries magnetization which is best interpreted as …
