Crystal settling geology
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: 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 …
