'''Shatter cones''' are rare geological features that are only known to form in the [[bedrock]] beneath [[meteorite]] [[impact crater]]s or [[Underground nuclear testing|underground nuclear explosions]]. They are evidence that the rock has been subjected to a shock with pressures in the range of 2-30 [[Pascal (pressure)|GPa]].<ref name=French1998>{{cite book
