Shock metamorphism or impact metamorphism describes the effects of shockwave related deformation and heating during impact events. The formation of similar features during explosive volcanism is generally discounted due to the lack of metamorphic effects unequivocally associated with explosions and the difficulty in reaching sufficient pressures during such an event.May 25, 2016 Shock metamorphism or impact metamorphism describes the effects of shockwave related deformation and heating during impact events.

Shock Metamorphism (Impact Metamorphism) They result from metamorphism of limestones and dolostones. Some foliation may be present if the marble contains micas. Eclogites: These are medium to coarse grained consisting mostly of garnet and green clinopyroxene called omphacite, that result from high grade metamorphism of basic igneous rocks

ones. Shock metamorphism is also characterized by a progressive destruction of original textures with increasing shock pressure, a process that eventually leads to complete melting or vaporization of the target rock (Figs. 4. 3, 4. 4, and 4. 5). 4. 2. STAGES OF SHOCK METAMORPHISM The fact that different shock pressures produce a variety Thus, the range of shock metamorphism is from 0. 02 to 1 megabar these pressures are known to occur in the Earth only in its mantle and core but the rock types affected by shock metamorphism are dominantly those of the crust where the natural pressure gradient achieves values less than those affecting shocked rocks.shock metamorphism results from Shock metamorphism of clay minerals on Mars by meteor impact Joseph R.

How can the answer be improved? shock metamorphism results from The following is a discussion of the timescales for these different secondary alteration processes inferred from various longlived chronometers, although the boundaries between these processes are not always well defined (e. g. , an energetic impact event on a planetesimal may result in shock metamorphism as well as thermal processing). Shock Metamorphism When a large meteorite collides with the Earth, the kinetic energy is converted to heat and a high pressure shock wave that propagates into the rock at the impact site. The heat may be enough to raise the temperature to the melting temperature of the earth rock. and would result in metamorphic rocks belonging to the Impact Metamorphism Processes. Shock metamorphism, also called impact metamorphism, occurs when high heat and pressures generated during an impact deform the underlying rock layers. Shock metamorphism can lead to planar deformation features, highpressure polymorphs, and shatter cones, all of which provide evidence supporting a bolide impact.
