| Description |
Shattercone in rock from the 1.85 billion year-old Sudbury Impact Structure in Ontario, Canada. (public display, Cleveland Museum of Natural History, Cleveland, Ohio, USA) Shattercones are striated conical structures in rocks formed 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 the apex of the cones pointing toward the direction of the incoming object (i.e., upward - toward space). |
