Question

Quizplus · Accepted Answer

The term "aureole" is commonly used to describe the region of thermally metamorphosed rock surrounding a cooled pluton. This area is typically characterized by changes in the texture, mineralogy, and fabric of the surrounding rock due to exposure to high temperatures and pressures. The other options (shear zone, oriole, oleo) do not accurately describe this process or feature.
