Summary
editDescriptionShattercones (Middle Miocene, 15 Ma; Steinheim Impact Structure, Germany) 1.jpg |
English: Shattercones from the Miocene of Germany.
Shattercones are striated conical structures in rocks formed during an impact event as a powerful shock wave or pressure front moved through. 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). |
