What is equilibrium crystallisation?

1. Equilibrium crystallization: crystals form from a cooling melt in a closed system (i.e., no eruptions of magma out of the system or injections of fresh melt into the system). Chemical equilibrium is maintained until the melt has completely crystallized.

Correspondingly, what is magma mixing?

Magma mixing or mingling is a popular hypothesis, generally proposed in terms of blending between a crustal melt and mafic material from the mantle that caused that melting. Is gold a lithophile? Given a system where all three melts are in equilibrium (i.e. molten Fe-Ni, sulphide and silica magma), a lithophile element, such as potassium, will be in highest concentration in the silica magma; whereas a siderophile element, such as one of the precious metals: platinum, palladium or gold; will be most enriched in

Thereof, what are goldschmidt rules?

Goldschmidt who formulated the Goldschmidt Rules to describe partitioning of trace elements between solids and melt: (1) If two ions have similar ionic radii and the same charge, the smaller ion will be preferentially concentrated in the solid; (2) If two ions have similar radii but different charges, the ion with the You can also ask is iron a lithophile? Several transition metals, including chromium, molybdenum, iron and manganese, show both lithophile and siderophile characteristics and can be found in both these two layers.

Keeping this in consideration, is nitrogen a lithophile?

N is lithophile during Earth's core formation. The reduced mantle is a major N reservoir on present-day Earth.
