The International Union of Geological Sciences (IUGS) classification of igneous rocks is a widely accepted system that categorizes these rocks based on their mineral composition, texture, and mode of occurrence. This classification provides a systematic framework for geologists to understand and communicate information about igneous rocks, which are formed from the cooling and solidification of molten magma.

The IUGS classification divides igneous rocks into two main categories: plutonic (intrusive) and volcanic (extrusive). Plutonic rocks form beneath the Earth's surface through the slow cooling of magma, while volcanic rocks form on the Earth's surface through the rapid cooling of lava. Each of these categories is further subdivided based on the mineral composition, texture, and other characteristics of the rocks.
