What is plutonic definition?

The term plutonic refers to rocks or geological features that form deep within the Earth's crust. These rocks are formed by the slow cooling and solidification of magma or lava, which is located deep within the Earth's mantle and rises to the surface through volcanic activity. Plutonic rocks are characterized by their coarse-grained texture and are typically made up of minerals such as quartz, feldspar, and mica. The term plutonic is derived from the Greek word "Pluton", which means "god of the underworld". Plutonic rocks are also known as intrusive rocks because they intrude into existing rocks and often form large, irregular masses. Some common types of plutonic rocks include granite, gabbro, and diorite.
