WebFractional crystallization in silicate melts ( magmas) is complex compared to crystallization in chemical systems at constant pressure and composition, because changes in pressure and composition can have dramatic effects on magma evolution. WebMagma also varies in temperature, and in how much dissolved gas it contains. All of these factors control the viscosity of the magma (whether it is relatively runny or very thick and sticky). Viscosity, in turn, controls …

Magmatic water, also known as juvenile water, is an aqueous phase in equilibrium with minerals that have been dissolved by magma deep within the Earth's crust and is released to the atmosphere during a volcanic eruption. It plays a key role in assessing the crystallization of igneous rocks, particularly silicates, as well as the rheology and evolution of magma chambers. Magma is composed of minerals, crystals and volatiles in varying relative abundance. Magmatic differentiation varies …

WebSep 27, 2012 · That magma slowly starts to cool and form crystals; because the crystals don’t use up the silica in the same proportion that exists in the magma, the remaining liquid magma becomes slowly more silica-rich. Understanding this process helps us “see” where these magma storage areas are.
