Crystal fractionation definition
WebJun 8, 2024 · Fractionation or fractional crystallization is another process that increases the magma silica content, making it more felsic [ 9 ]. As the temperature drops within a magma diapir rising through the crust, some minerals will crystallize and settle to the bottom of the magma chamber, leaving the remaining melt depleted of those ions. WebIt is commonly believed that both processes are very efficient and do not cause much fractionation of the isotopes. From the Cambridge English Corpus Within these …

This is consistent with the low concentrations of K in the major crystal-lization phases of mafic magmas (e.g., olivine and pyroxene), leaving the K isotopic system in melts undisturbed. By contrast, scarce data for high-silica granites suggest slightly more variable and lighter K
WebThe process of melt–crystal separation that could cause large-scale magma fractionation involves two contrasting styles of transportation; one is the motion of crystals in a melt-dominated environment (e.g. crystal settling or flotation in a melt) and the other is motion of melt in a crystal-dominated state (e.g. permeable flow in a crystal mush).
