Inhomogeneous deformation in roses granodiorite, N.E. Spain

Abstract

Evidence is presented for extreme heterogeneity of deformation intensity in the Rosesgranodiorite during thelate-Hercynian. A weak foliation was first developed and was deflected into a major zone of anastomosing ductile shear zones of variable width and finite strain. In the later stages of the deformation more bnttle shear zones developed. It is proposed that al1 the structures in the Roses granodiorite were produced during the same deformation event as progressive uplift of the region occurred.
