Batholiths are the largest of all igneous intrusions. They are formed by the massive invasion of hot magma into country rock. Such a large intrusion can melt or metamorphose most rocks. Cooling of the magma can take thousands of years. Like dikes, batholiths cut through pre-eexisting rocks, so they are discordant intrusions.

Characteristics A body of intrusive igneous rock which crystallizes from magma cooling underneath the surface of the Earth is called a pluton.If the pluton is large, it may be called a batholith or a stock depending on the area exposed at the surface. If the body has an exposed surface area greater than 100 km2, then it’s a batholith, otherwise it’s a stock.
