Question

Quizplus · Accepted Answer

The term "pluton" refers to a body of intrusive igneous rock that formed from magma that cooled and solidified beneath the Earth's surface. Therefore, the contact surrounding the pluton would also be intrusive, meaning that the surrounding rock was intruded by the cooling magma. Options B and C refer to sedimentary processes and would not be appropriate for describing a pluton. Option D refers to a type of rock boundary formed by movement along a fault, which is also not applicable to the surrounding contact of a pluton.
