ABSTRACT In the Hercynian belt of Brittany (France), large localized shear zones indicate dextral transcurrent shearing. In this letter regional Hercynian structures and their relationships

with shearing are considered and information obtained by quartz fabric analysis in the central part of the belt, outside the major shear zones, is presented. Fabric patterns show that a

dextral shear component is associated with Hercynian penetrative deformation. Existing geological data are reconsidered in the light of these results, and the extent to which the Hercynian

belt of Brittany can be regarded as a ‘major shear zone’ is discussed. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution
