“…A radial distribution of deformation paths may be a common feature in secondary or progressive arcs (sensu Weil and Sussman, 2004) where the strain trajectories, initially parallel within a rectilinear mountain belt, tend to diverge (or converge) following to subsequent oroclinal bending (e.g., Speranza et al, 1997;Marshak, 2004;Yonkee and Weil, 2010;Weil et al, 2010;Gutiérrez-Alonso et al, 2012;Pastor-Galan et al, 2012;Johnston et al, 2013). Conversely, in primary arcs (sensu Weil and Sussman, 2004) where no oroclinal bending is involved, both a uniform and radial strain field can exist .…”
