Meteorite shock stage
Videos
Meteorite shock stage is a measure of the degree of fracturing of the matrix of a common chondrite meteorite. Impacts on the parent body of a meteoroid can produce very large pressures. These pressure
Shock stationed clay mineral from the Puchezh-Katunsky meteorite crater
Shocked quartz with two sets of "decorated" planar deformation features in impact melt rock from the Suvasvesi impact crater. Planar deformation features are only produced by extreme shock compressions on the scale of meteor impacts. They are not found in volcanic environments.
Impact-fractured granite (orangish areas - K-feldspar & quartz) with grayish- to blackish-colored impact pseudotachylite (impact melt) vein fillings
Shock metamorphism
Videos
Shock metamorphism or impact metamorphism describes the effects of shock-wave related deformation and heating during impact events.
