Shatter Cone Impactite | 14 grams | Rochechouart Impact Structure | France | SO24 Variscite The material left to pickThis is a fantastic shatter cone from France weighing 14 grams and measuring 36x20x14 mm. Although not a meteorite, impactites and shatter cones are directly linked to them and their impacts. Shatter cones are evidence that the rock has been subjected to an extreme shock with very brief high pressures. Shatter cones are rare geological features that are only known to form in the bedrock beneath large meteorite impact craters. They have a distinctively
