Question

Quizplus · Accepted Answer

Hornfels is the correct answer because it is a nonfoliated metamorphic rock that forms through the contact metamorphism of fine-grained rocks like shales, mudstones, or volcanic rocks. This process occurs when these rocks are subjected to high temperatures and pressures from nearby magma bodies, but without significant deformation or compression, leading to the formation of a dense, hard rock without a layered or banded appearance.
