Chemical quenching can also be an important process during the final stages of pegmatite crystallization, whereby a fluxing element reaches saturation through continuous fractionation or another process (e.g., Alfonso and Melgarejo, 2008; Barros et al., 2020; Kaeter et al., 2021). The crystallization of minerals containing these fluxes …

Pegmatite is an extremely coarse-grained intrusive igneous rock composed of large interlocking crystals. There is no defined mineralogy for pegmatite; any plutonic rock may form pegmatite. The most common type of pegmatite is made of granite. Granite pegmatite typically contains feldspar, mica, and quartz. Pegmatite is an …
