Question

Quizplus · Accepted Answer

A pluton is a type of intrusive igneous rock that forms when magma solidifies within the Earth's crust. Plutons can range in size from small dikes and sills to large batholiths, and their shapes can be irregular or blob-shaped depending on how the magma chamber cooled. Xenoliths are fragments of pre-existing rock that get incorporated into an igneous rock as it forms, while a batholith is a large, dome-shaped pluton that covers an area of at least 100 square kilometers. Lava plateaus are formed from extensive lava flows that cover large areas of land, but they are not intrusive igneous rocks that form from magma chambers.
