Molten material within the Earth is called magma. In simple terms magma can be thought of as molten rock. When magma cools, it solidifies to form rock which is called igneous rock. That is deceptively simple, since the solidification process can be very complex.There is a considerable range of melting temperatures for different compositions of magma.agma. Magma is the term used to describe molten material within the Earth; in simple terms: molten rock. But the molten rock usually contains some suspended crystals or dissolved gases.
Filter-pressing, process that occurs during the crystallization of intrusive igneous bodies in which the interstitial liquid is separated from the crystals by pressure. As crystals grow and accumulate in a magmatic body, a crystal mesh may be formed, with the remaining liquid distributed in the interstices. This mesh may result from crystals that sink to the floor of the magma chamber or from crystals that accumulate during the advanced stages of crystallization of the body.
