Interplay of downbuilding and gliding in salt-bearing rifted margins: insights from analogue modelling and natural case studiesInterplay of downbuilding and gliding in salt-bearing rifted margins: insights from analogue modelling and natural case studies

Our analogue modelling programme simulates a thermally subsiding rifted margin with a regional late syn-rift to early post-rift salt basin. End-member models included i) pure downbuilding in a confined salt basin and ii) dominant gliding on a tilted opened toe margin. The spectrum between these was...

description Our analogue modelling programme simulates a thermally subsiding rifted margin with a regional late syn-rift to early post-rift salt basin. End-member models included i) pure downbuilding in a confined salt basin and ii) dominant gliding on a tilted opened toe margin. The spectrum between these was completed by modelling different amounts of downbuilding vs. dominant gliding. Our results provide structural geometries and tectono-stratigraphic architectures for salt structures related to those end-member processes, as well as when these occur simultaneously. Downbuilding is represented by vertical aggradation of syn-kinematic strata, the erosional truncation of megaflaps, and syn-kinematic debris sourced from salt and pre-kinematic strata. Dominant gliding is represented by salt-detached extension and related diapirism, resulting on the progressive increase in line-lengths of younger stratigraphic units.
