Product Description

Giant Kentland Indiana Shatter Cone - New!
This is a beautiful, classic shatter cone, fantastic ivory white, from Kentland, Indiana. This shatter cone has the characteristic, clearly visible "horsetailing." Shatter cones are conical fractures with typical markings produced by shock waves that leave indelible markings on rocks affected by a meteorite or comet impact with the earth.

They have been observed in rocks shocked in explosions of nuclear tests and have experimentally been produced in the laboratory. The required shock pressure is estimated between roughly 20 and 200 kbar with the apex of the cones pointing to the shock source, but irregular orientations and even counter orientation are frequent. In impact structures, the size of the cones is between centimeters and meters. Fully developed cones are rare which is explained by rock inhomogeneities. In extreme cases, shatter cones may degenerate into shatter cleavage (in slaty rocks).

This is a great museum display specimen!

Ships with information, Kentland Indiana shatter cone tag, and Certificate of Authenticity. Stand included. Photographic cube is not.
