The classification of igneous rocks has been the subject of frequent debate and voluminous literature. Over the past decade, most geologists have accepted the IUGS (International Union of the Geological Sciences) classification as the standard.

Classification of igneous rocks is one of the most confusing aspects of geology. This is partly due to historical reasons, partly due to the nature of magmas, and partly due to the various criteria that could potentially be used to classify rocks.

"Igneous rocks form when molten magma cools and solidifies. This molten rock is made up of elements found in the silicate minerals, water vapor, and other gases, which are all confined in the magma by the pressure of the surrounding rocks." (Johnston, Aber & Ye, 1996, p. 9)

Igneous rocks (from Latin "ignis" meaning "pertaining to fire") are formed by cooling and solidification of molten rock material and typically represented by an interlocking aggregate of silicate minerals. ... Classification of plutons is based on:
