Abstract

The great majority of Moine lineations are mica structures, and together with a parallel preferred orientation of epidote [010]-axes, are directed mainly into the south-east quadrant. This orientation is retained within the crush zone alongside the Moine Thrust. The regional preferred orientation of muscovite [100]-axes and [001]-axes is consistent with north-east and south-west movements except within the crush zone where fabric reorientation suggests movements normal to this direction. The growth of albite textures and fabric is intimately associated with thrust plane movements, the preferred orientation of albite suggesting a south-east and north-west vertical plane of deformation.
