Triassic salt was only observed in the northwestern part of the offshore Tarfaya Basin; but this interval is denoted as "Triassic evaporitic events" in the summary by Wenke (2014), and these thick salt deposits led to salt diapirs in those offshore regions later. The other basin settings were arid at this time. This interval was terminated by the end-Triassic (CAMP) basaltic extrusives and doloritic sills (not given a separate "Fm" here).
