Abstract

JAPAS, M.S  and  RE, G.H. Neogene tectonic block rotations and margin curvature at the Pampean flat slab segment (28º-33º SL, Argentina). Geoacta [online]. 2012, vol.37, n.1, pp.01-04. ISSN 1852-7744.

Available paleomagnetic data from the Pampean flat slab segment reveal a heterogeneous rotation pattern that is interpreted herein as the result of the overprinting of late NNW-WNW left-lateral brittle-ductile megashear zones that would be also responsible for the continental margin bending.

Keywords : Paleomagnetism; Transpressional and transtensional belts; Precordillera; Subduction of aseismic ridges.
