Influence of inherited rifted margin architecture on continental collision dynamics

Continental collision is a key process in lithospheric evolution, driving mountain building, crustalthickening, and supercontinent assembly. Within the Wilson cycle, collision marks the finalstage following rifting, ocean spreading, and subduction. Early rifting and rifted margindevelopment precede...
