The work of Mescua and Giambiagi (2012) addressing a case study in the Malargüe fold-and-thrust belt in the Argentinian Andes raises a controversy over two structural models: inversion vs. new thrust generation. The authors examine the potential inversion of Mesozoic normal faults using numerical modeling and discuss contrasting geological arguments in the literature dealing with mechanisms of basement involvement in deformation, analyzing some structural cases ?suspected of being inverted normal faults?. Since Mescua and Giambiagi (2012) attribute the alleged source of the controversy to us (Dimieri, 1997; Turienzo, 2010), we would like to clarify our point of view and to explain our different approach to the subject.
