Quick Summary

A pull-apart basin is a geological landform characterized by a rectangular or rhomb-shaped depression with steep sides. These basins are formed by the extension of the Earth's crust, specifically related to strike-slip faults. When nearly parallel strike-slip faults move horizontally past each other, the crust in the region between them is pulled apart, creating a gap that forms the basin.1

Examples of pull-apart basins include the Dead Sea and California's Imperial Valley. These basins are significant geological features where crustal extension occurs due to the lateral movement along major fault lines.1
