The definition of magma
WebVolatile Content: Magma invariably contains small amounts of dissolved gas (water, CO 2 etc) which is released as pressure is removed. Magmas formed by melting of mantle rocks have generally low volatile contents, but those formed by partial melting of crustal rocks are often volatile-rich. A high volatile content decreases viscosity (like ... Webnoun. : the underground space usually deep below the earth's surface occupied by magma that may ascend from it to or toward the surface.
