WebCrystal phases are suspended and exsolved fluids may be present too. We define a crystal-dominated regime as a mush, a term now widely used in the petrological and geophysical literature. The crystalline component forms a framework and melt (±fluid) is distributed as a network between the crystals. WebCrystal Settling/Floating - In general, crystals forming from a magma will have different densities than the liquid. If the crystals have a higher density than the liquid, they will tend to sink or settle to the floor of the …

Fractional Crystallization - an overview ScienceDirect Topics

Fractional crystallization, or crystal fractionation, is one of the most important geochemical and physical processes operating within crust and mantle of a rocky planetary body, such as the Earth. It is important in the formation of igneous rocks because it is one of the main processes of magmatic differentiation. Fractional crystallization is also important in the formation of sedimentary evap… WebDefinition of crystal flotation. The floating of lighter-weight crystals in a body of magma.

Definition of crystal settling - Mindat.org

WebCrystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and … WebCrystal settling is the settling down of crystals in the magma in which they formed due to gravity. When crystals are newly formed in magma, they settle, leaving space for more … WebFeb 24, 2024 · These data indicate that crystal settling by gravitation is not the only mechanism dominating granitic differentiation.
