Attitude variation of en echelon fractures in generalized Riedel experiments

    Research output: Contribution to journalMeeting abstractpeer-review


    One of the interesting characteristics of en echelon fracture systems is the wide range of dihedral angles they display between individual fractures and the plane of the parent array. For en echelon veins this is from almost 0 ° up to about 85 °. This note reports a series of simple experiments which are designed to test the writer's theoretical prediction that the angle of fracture propagation is variable and depends on the degree to which the material in the shear zone dilates or contracts during the deformation (incremental dilational shear hypothesis).
