Document Summary
Once molten and upon cooling, the magma (molten rock) crystalized into solid rock. Magma is molten rock in the interior of the planet. Lava is the molten rock on the surface of the planet. You have to increase the temperature or increase the pressure. Crystallization the process of formation of solid crystals precipitating from a solution, melt or more rarely deposited from a gas. Pure substances the solidus and liquidus are the same and referred to as the melting point. Partial melt - slush between solidus and liquidus line. Silicates uses sio: can separate silicate minerals into two types of minerals, fe + mg rich. Forms into pyroxene, you lose some olivine in the formation of pyroxene. These are the basic minerals that come out of a magma chamber that form igneous rocks! Quartz last to crystalize, first to melt.
