Palaeomagnetism of Late Precambrian or Cambrian diorites from Leicestershire, U.K.

Af demagnetization of the Late Precambrian or Cambrian diorites of Leicestershire reveals at least two components of magnetization in sites with stable, coherent NRM. A high remanentcoercivity component yields a palaeomagnetic pole at 141° E 63° N (A959 = 9°) in agreement with results from other Late Precambrian or Cambrian rocks in North Wales and Norway. A softer component may be of recent viscous origin, or have been acquired during Cambrian remagnetization.
