Shatter cone in granite, Nördlinger RiesYour model is disabled. For more details go to Edit properties3D Model
A shatter cone is a geological deformation feature created during impacts. They form under pressures of about 2-30 GPa when the shock wave propagates through the rock. Shatter cones usually devellop pourly in coarser grained rocks. This makes shatter cones in granite quite rare for the Nördlinger Ries crater: very few have been found and they have not been described in literature. These features are the only macroscopic indicator of the effects of a large meteorite impacts that can be see with the unaided eye (i.e., without a petrological analysis under a microscope).
