Which mechanism causes sediment accumulation in pull-apart basins along strike-slip faults?

💡 Explanation

When strike-slip movement occurs along transform faults, pull-apart basins form because localized crustal extension induces thinning and subsidence, creating topographic lows that trap sediment. Therefore sag basins forming results, rather than reverse drag, tilted blocks, or horst-graben structures which arise from different tectonic compressional regimes.
