Summary

[edit]
Description

Shattercone in rock from the 1.85 billion year-old Sudbury Impact Structure in Ontario, Canada. Shattercones are features developed in rocks by a powerful shock wave or pressure front moving through during an impact event. They have a three-dimensional cone-like structure, with the points of the cones directed toward the shock wave origination site. Undisturbed shatterconed rocks will have their cones pointing upward (toward space).
