perature rise due to frictional heating. This frictional heating is generated in a way similar to rubbing both hands together. However, solidified friction melts (pseudotachylyte) are the only unambiguous signature of seismic slip along natural faults but are rare in the geologic record. This has led the scientific community to question whether thermally activated mechanisms, observed during laboratory experiments and modeled in theoretical studies, are also relevant for the mechanics of natural, seismic faults. This has created a paradox that is arguably one of the most debated topics in the Geosciences. In our Geology manuscript we show a gamut of new natural fault rocks that are the unambiguous signature of thermal processes active during earthquake slip.


Isotopic shifts in the Cenozoic Andean arc of central Chile: Records of an evolving basement throughout cordilleran arc mountain building
Marcia Muoz et al., Departamento de Geologa, FCFM, Universidad de Chile, Casilla 13518, Correo 21, Santiago, Chile. First published on 28 June 2013, http://dx.doi.org/10.1130/G34178.1

Late Cenozoic arc magmas from central Chile have been formed during the construction of the modern Andes. This archetypical example of a cordilleran arc orogenic system has been built over an heterogeneous basement and a significant volume of continental lithosphere has ben underthrusted under the arc area due to shortening processes. Based on Hf and Nd isotopic data along with the latest orogenic models for the region, this contributions shows that major magmatic isotopic shifts are related to different basement domains and also to the evolution of such basement throughout the assemblage of the modern Andes. In particular, such isotopic shifts signal the arrival of older basement to the crustal magmatic source resulting from the deep western underthrusting responsible for the main Andea
