Cambrian geology of the Salt Range of Pakistan: Linking the Himalayan margin to the Indian craton (original) (raw)
GSA Bulletin
In our 2019 paper on the Salt Range of Pakistan (Hughes et al., 2019, p. 1108), we wrote, “Recognizing significant geological differences between neighboring rocks separated by a major high-strain zone is, according to Martin (2017, p. 62), fundamental to terrane recognition.” Martin’s (2017) contention had been that the Salt Range thrust provides such a case, but his response to our paper reports no data suggesting significant geological differences across this structure. To do so would be challenging because, as we reported in our paper (Hughes et al., 2019), two boreholes drilled on either side of the thrust, located less than 25 km apart, reveal the same stratigraphy in terms of the rock succession, unit thickness, detrital zircon spectra, and depositional age of both hanging-wall and footwall rocks (Siddiqui, 2012, fig. 5; Hughes et al., 2019, figs. 3, 4, 11, and 12). The suite of rocks shared on both sides of the fault includes a distinctive 1000-m-thick evaporite succession, ...
