Etymology:
"Plutonic" is derived from the Greek word "Plouton," the name of the Greek god of the underworld, Hades.
Meaning:
Plutonic refers to geological processes that occur deep within the Earth's crust, where rocks are subjected to high temperatures and pressures and undergo significant changes in their mineral composition and texture.
Origin:
The term "plutonic" was first used in geology by the Scottish geologist James Hutton in 1795. Hutton proposed that rocks could form from molten material deep within the Earth, which he believed erupted as volcanoes and then cooled and solidified to form intrusive igneous rocks. He named these deeply formed rocks "plutonic" after the Greek god associated with the underworld.
Characteristics of Plutonic Rocks:
Plutonic rocks are formed from magma that cools and solidifies slowly over millions of years beneath the Earth's surface. They are typically coarse-grained and crystalline, as the minerals have time to grow and interlock during the cooling process. Plutonic rocks include:
