Which mechanism causes long-term subsidence in sedimentary basins along active strike-slip faults?

💡 Explanation

When strike-slip occur, local restraining bends creat compressional forces resulting in localised uplift alongside other areas experiencing tectonic wedging; this compacts the accumulating sediments in between. Therefore accelerated compaction occurs at the stepover locations, forming a structural mechanism for localised depression which is the best answer, rather than alternatives involving long-term distributed processes.
