Question

Quizplus · Accepted Answer

Batholithic-sized plutons are large masses of igneous rocks that cooled and solidified deep beneath the earth's surface. These plutons are typically composed of granitic rocks, which are coarse-grained and rich in quartz and feldspars. Obsidian is a glassy volcanic rock and is typically found in smaller volcanic features. Basalt is a common extrusive rock that is often associated with volcanoes and is different in texture, mineralogy, and chemistry compared to granite. Sandstone is a sedimentary rock and is not associated with the formation of plutons.
