An international research team led by The University of Manchester analyzed magma from the 2021 Tajogaite eruption on La Palma, Spain. The scientists found that “superheating,” which occurs when magma becomes hotter than the temperature at which crystals remain stable, can postpone crystal formation as the magma moves toward the surface.

Superheating Removes Crystal Seeds

The study, published in Nature Communications, found that intense heat can dissolve tiny existing crystals that normally act as “seeds” for the growth of new crystals.
