Question

Quizplus · Accepted Answer

Migmatites are rocks that have undergone partial melting, resulting in a mixture of igneous and metamorphic textures. This means that there will be visible textural evidence of melting, such as the presence of veins of igneous material within a metamorphic matrix. Marbles, porphyroblastic hornfels, and coarse-grained angular fault breccias are all metamorphic rocks, but they do not typically exhibit visible evidence of partial melting.
