Tectonic characterization of the mesoscopic kinking from the Sierras Australes of Buenos Aires

Mesoscopic kinking formed in cleaved rocks of the Hinojo, Providencia, Lolen and Sauce Grande Formations and mylonitic bands within basement rocks are described. Angular relationships between the obtuse bisectors in conjugate compressive kink fold sets and the planar anisotropy (cleavage) are relate...
