Question

Intrusive igneous rock bodies are called ?

Answer 1

Intrusive igneous rock bodies are called plutonic or intrusive rocks, comprising coarse-grained minerals like granite and diorite, formed from slowly cooled magma deep underground.

Step-by-step explanation:

Intrusive igneous rock bodies are called plutonic or intrusive rocks. These rocks are formed when magma cools slowly deep beneath the Earth's surface and as a result, they are characteristically coarse-grained. Examples of intrusive igneous rocks include granite, which is composed largely of light-colored minerals, and diorite, which contains a mix of light and dark minerals. The presence of large, well-formed crystals is a signature feature of these rock types, a consequence of the slow cooling process allowing for the growth of substantial crystal structures.

Answer 2

Large bodies of magma that solidify underground before they reach the surface of the crust are called plutons. Coarse-grained intrusive igneous rocks that form at depth within the earth are called abyssal while those that form near the surface are called subvolcanic or hypabyssal.
