1889 Geol. Mag. 243 Rosenbusch..seeking to bring clearly into view the consideration that the special kind of metamorphism referred to is only produced when the mechanical forces effect movement, and thus do work, suggested the term Dynamical metamorphism or dynamometamorphism.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) VIII. 296a/2 Cataclastic rocks are mechanically sheared and crushed. They represent products of dynamometamorphism, or kinetic metamorphism.
