Faulting

Tectonics and Volcanism

The fracturing of rock along a surface where the two sides have moved relative to each other, releasing accumulated tectonic strain. Faults are classified by their motion as normal, reverse or strike-slip, and the sudden slip along a fault plane is the direct mechanical cause of most earthquakes.

Quote, Shaped: Davis Strait, Geology
The Davis Strait is underlain by complex geological features of buried grabens (basins) and ridges, formed by strike-slip faulting of the Ungava Fault Zone during Paleogene times about 45 million to 62 million years ago.
