A) slate
B) gneiss
C) breccia
D) mylonite

Question

Quizplus · Accepted Answer

Metamorphism caused by shear stress without changes in temperature or pressure results in the formation of mylonite. Mylonite is a fine-grained, compact rock created by shearing and crushing, with particles that are elongated and aligned in the direction of the shear. Slate is a low-grade metamorphic rock resulting from the regional metamorphism of shale or mudstone, while gneiss is a high-grade metamorphic rock formed from the recrystallization of granite or other igneous rocks. Breccia is a sedimentary rock consisting of angular fragments of various rock types that are cemented together.
