Faults in the southeastern rim of Haughton

Location:
Southeastern rim of the impact structure
Scale: Height of the rocks above the ground is approximately 30-35 meters

Here's more evidence of faulting at Haughton. You can see quite clearly in photo above that the rocks on the right side of the fault surface have slid and dropped down relative to the rocks on the left side of the fault (see picture below for more explanation). Because of the massive amount of energy generated during an impact and all the material that is moved and thrown around, faults are a common geologic feature at impact crater sites around the world.

Annotated photograph showing a series of faults dipping outwards from the crater center. The solid and dashed lines represent faults and bedding surface, respectively. The numbers above the faults show the amount of movement that occurred on that particular fault. This figure is modified from figure 11 in Osinski G.R. and Spray J.G., Tectonics of complex crater formation as revealed by the Haughton impact structure, Devon Island, Canadian High Arctic. Meteoritics and Planetary Science, 2005.
