Classifying curved orogens based on timing relationships between structural development and vertical-axis rotations

The role of oroclinal bending in the structural evolution of the Central Anatolian Plateau: evidence of a regional changeover from shortening to extension

“…These structures attain their curvature progressively throughout a mountain belt's deformation history. All types of orogenic curvatures can be determined by paleomagnetism because of the ability to obtain the path and amount of rotation of each block around a vertical-axis (Schwartz & Van der Voo 1984;Eldredge et al 1985;Weil & Sussman 2004). Paleomagnetic results may also be correlated with kinematic data in order to assess the spatiotemporal trends of deformation of a mountain belt.…”

“…The Japan, Mariana, Carpathian, Aegean, Cypriote arcs, the Himalayan collision zone or the non-collisional Bolivian orocline, are well-known examples of such features. Weil & Sussman (2004) classified these curved structures into three main categories considering their origin and evolution. The first group constitutes "oroclines".…”

Constraints on deformation of the Southern Andes since the Cretaceous from anisotropy of magnetic susceptibility

“…Conversely, in primary arcs (sensu Weil and Sussman, 2004) where no oroclinal bending is involved, both a uniform and radial strain field can exist . Key to better interpret our results within a regional tectonic framework is to understand the real nature and origin of the orogenic bend of the Southern Andes.…”

“…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 .…”

Introduction: Palaeomagnetism in fold and thrust belts: new perspectives

“…Since the pioneering applications of authors such as Norris & Black (1961) and Tarling (1969), palaeomagnetism has been applied to problems at a variety of scales in many orogenic systems (e.g. Elredge et al 1985;Kissel & Laj 1989;Weil & Sussman 2004;Elmore et al 2012). In particular, palaeomagnetic data have been increasingly used as key quantitative information for determining the timing, distribution and magnitude of vertical axis rotations (Van der Voo & Channell 1980;McCaig & McClelland 1992;Allerton 1998).…”
