Conjugate Shear zone convergence in Lower Carboniferous Limestone. Mumbles Head, Gower, Wales.
Late Variscan Orogeny deformation. Cleavage deflection occurs as the two shear zones propagate past one another - they form contemporaneously and alter the sense of shear experienced and therefore rotate the cleavage formed in the centre of convergence. In the photo above the left (Easterly) portions of the two shear zones show relatively shallow cleavage orientations becoming steeper in the centre of convergence (right hand side) where they are rotated toward the shear sense of the crosscutting shear zone. Both of these shear zones remained active throughout the convergence.
Cleavage forms in the long axis of a strain ellipse and is progressively rotated toward the orientation of the maximum compressive strength, sigma1. They can be used to interpret sense of shear, the lower shear zone above shows top-to-the-right rotation, a dextral shear sense.

Apparently Geology degrees sometimes involves looking at Anseriformes… so here’s a Red Breasted Goose I’ve been forced to deal with.
