WitrynaThe role of water in metamorphism is determined by the independent variables rock pressure, temperature, water pressure, and the amount of water present. An analysis of the possible events that evolve in the regional metamorphism of an argillaceous sediment indicates that, if water flow takes place via pore spaces connected to the … Witryna9 sty 2024 · The Simlipal structure is possibly the remnant of a large complex impact crater having an original diameter of at least 50 km. Although zircons from an impact melt rock furnish a concordia age of 3107±14 Ma, in the absence of any unambiguous shock metamorphic effects in them, it is difficult to assign the age to the impact event.

Shock metamorphism or impact metamorphism describes the effects of shock-wave 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.
