Editorial for the special issue “Mineral textural and compositional variations as a tool for understanding magmatic processes”

This Special Issue of Minerals collects seven different scientific contributions highlighting how magma chamber processes and eruption dynamics studied either in the laboratory or in nature may ultimately control the evolutionary histories and geochemical complexities of igneous rocks. The main purpose is to report novel results bearing on the most important mechanisms that govern the textural and compositional changes of minerals and their host rocks. Different scenarios and case studies are presented here regarding the polybaric–polythermal solidification of magmas under either closed or open conditions. Results from these scientific contributions have the potential to elucidate those physicochemical parameters which play key roles in crystallizing systems, when degassing, magma mixing, and magma–fluid–crust interaction phenomena take place over different temporal and spatial scales.
