GUTIERREZ, Adolfo Antonio  and  MON, Ricardo. Kinematic macroindicators in the Ambato Block, provinces of Tucumán and Catamarca. Rev. Asoc. Geol. Argent. [online]. 2008, vol.63, n.1, pp.24-28. ISSN 0004-4822.

At the eastern-most Andean foreland (65°30'-66°15'W y 27°30'-28°30'S) the Ambato Block mountain shows a NW orientation which differs from the common NE regional strike, at this part of the Pampean Ranges. The present-day morphotectonics configuration of the Ambato Block is due to a Pleistocene synistral shear zone along the major north/south Andean faults. Kinematic macroindicators identified are: second order Riedel fractures, transpressive structure like deformation wedges and pull-apart basins, rotational faults, normal faults, inverse faults and eliptic structures.

Keywords : Tectonics; Normal faults; Kinematic macroindicators.
