A distinctive suite of deformation microstructures characterises iceberg-keel scoured diamicton.
- ass="label">•
This suite of structures is different from the suites of microstructures related to subglacial tills and mass-wasting deposits.

Characterising the effects of iceberg scour in diamicton is important more widely to inform: i) reconstruction of the geometry and dynamics of former ice sheets; and ii) installation and protection of offshore engineering structures in diamicton where iceberg scouring presents a geohazard.
