Abstract

We thank Jan Smit and colleagues (Smit et al., 2016) for giving us the opportunity to clarify some important points in our original manuscript (Font et al., 2016a) and to discuss the issues raised in their Comment. Their main critique centers on the origin of the mercury anomalies, which they argue are post-depositional and cannot be assigned to Deccan Traps activity. Their arguments center on the hypothesis of Lowrie et al. (1990) who invoked a process of downward infiltration by reducing waters to explain the origin of the white beds below the CretaceousPaleogene (KPg) boundary at Gubbio, Italy. Apparently Smit et al. are not aware of the work by Abrajevitch et al. (2015) or that this issue was addressed in our Geology paper. Here we provide more detailed explanations of why the comments by Smit et al. are out of date.  PDF
