WebCrystal settling would be another name for gravity settling. Step-by-step explanation In fractional crystallization processes, the crystals form and segregate themselves from the melt, or magma. By gravity, these denser particles, compared to the less dense melt, will settle at the bottom of the magma body where they accumulate in layers. Sources: WebMay 6, 2024 · Settling of ferromagnesian crystals from the upper part of the magma, and possible remelting of those crystals in the lower part can both contribute to the vertical zonation from relatively mafic at the bottom to more felsic at the top. From the perspective of volcanism there are some important differences between felsic and mafic magmas. dwayne westacott https://conservasdelsol.com
