Plutonic Geothermal Play Type

A pluton is a body of intrusive igneous rock that is crystallized by the slow cooling of magma. A plutonic geothermal play type is an area of heat surrounding plutons.[1]

For the Australian gold mine see Plutonic Gold MineIn geology, a pluton is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the surface of the Earth. Plutons include batholiths, stocks, dikes, sills, laccoliths, lopoliths, and other igneous bodies. In practice, "pluton" usually refers to a distinctive mass of igneous rock, typically several kilometers in dimension, without a tabular shape like those of dikes and sills. Batholiths commonly are aggregations of plutons. Examples of plutons include Denali, Cuillin, Cardinal Peak, Mount Kinabalu and Stone Mountain.The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite. Generally light colored, coarse-grained plutons of these compositions are referred to as granitoids.
