Shock-metamorphic transformations of rock-forming minerals of layered amphibolite of the southern Urals

In this work the patterns of shock-metamorphic transformations of rock-forming minerals (amphibole, plagioclase, and clinopyroxene) in layered crystalline schists (Southern Ural) appeared as a result of planar shockwave loading of rocks. Comparison of the data obtained with those of diaplect transformations of the above-listed minerals in the field and as a result of experiments with convergent spherical shockwaves for this rock revealed essential differences between transformations. The formation of polymineral shock-thermal apoamphibole and apoclinopyroxene aggregates that were typical for the conditions of spherical shockwave compression was not observed during stage shockwave compression, even at 52 GPa.
