概括
在诺森伯兰郡和达勒姆的36个地点进行了采样，该窗台被侵入到较低的二叠纪时代，被发现是磁性稳定的。 9和平均极点位于纬度37°·3 n经度168°·9 E.这些位点磁化的平均磁化方向的分布不是圆形的，而是椭圆形的，随着椭圆形的变化古磁经度的方向大约是古磁性纬度方向的两倍。
Summary
The Great Whin Sill, which was intruded in Upper Carboniferous to Lower Permian times, has been sampled at 36 sites in Northumberland and Durham. It was found to be magnetically stable, the site mean direction of magnetization being 187°·8–4°·9 and the mean pole position lying in latitude 37°·3 N longitude 168°·9 E. The distribution of the mean directions of magnetization at these sites is not circular but oval, with the variation in the direction of the palaeomagnetic longitude about twice that in the direction of palaeomagnetic latitudes. However the poles calculated from the site mean directions of magnetization have a circular distribution, and this observation leads to proposal of a method of calculating the errors associated with the palaeomagnetic pole positions.
