(a) Schematic view of the two possible fates for Triassic (pre-hyperextension) salt in a multistage rift system: the top-left panel shows no interference/reactivation between salt bearing basins (blue) and subsequent hyperextended systems (green); the top-right panel shows full interference/overprint of salt bearing basins during later hyperextension (modified from Miró et al., 2021). (b and c) Role of pre-rift salt during rifting and Alpine reactivation in the Asturias (b) and Basque-Cantabrian (c) transects (from Miró et al., 2021); Note that these sections are zooms on the sections displayed in Figure 6.
