Magmatism acts as a window to monitor the nature of mantle and crustal sources and also provides detailed records of the anatexis process and magma evolution, crust–mantle interaction, metallogenesis, and crustal growth and reworking events. In the last few decades, our understanding has been significantly extended regarding the specific tectonic settings and associated polymetallic deposits (e.g., Cu ± Mo ± Au mineralization) and their potential economic benefits. In addition, magmatism also results in devastating explosive eruptions that pose regional or global hazards (e.g., 2022 Hunga Tonga–Hunga Ha‘apai eruption). The origin, characteristics, evolution, and eruptibility of magmatic systems are therefore of great importance to our society.
A wide range of approaches has been carried out on the magmatic rocks to unravel the magma system evolution. Whole-rock and constituent minerals major, trace elements, and multisotope studies (e.g., Re-Os, Lu-Hf, Sm-Nd), coupled with U–Pb dating and in-situ Lu–Hf–O–Zr isotopic analysis of accessory phases (such as zircon, monazite, rutile or titanite) shed lights on firm evidence regarding the emplacement or eruption ages source magma, and their geodynamic evolution. Geophysical and geodetic observations provide critical snapshots or time series of physical conditions within the magma reservoirs and their surrounding host rocks. In addition, analytical and numerical simulations allow us to test a variety of concepts based on solid/fluid mechanics, thermodynamics, etc., and link multiple observations. With sequential data assimilation, the physics-based models can track the current evolution of a magmatic system and forecast its future unrest.
This Topical Issue welcomes studies to understand the processes during the magmatic system evolutions, including magma mixing, fractional crystallization, crustal contamination, and interaction with surroundings which controls the pre-eruptive unrest of volcanos. We especially encourage studies using interdisciplinary tools (e.g., geology, geochemistry, geochronology, geophysics, and numerical models) within but not limited to the fields of petrology, mineralogy, and economic geology to bring new insights into the magmatic system evolution.
