The IpGG aims to investigate the petrogenesis, evolution, and geodynamic significance of igneous rocks through integrated field, petrographic, mineralogical, geochemical, and geochronological approaches. By studying rocks from outcrop to thin-section and at the mineral scale, we seek to understand magmatic processes, including magma generation, differentiation, crust–mantle interaction, magma mixing, and the emplacement of mafic to felsic magmas. Particular emphasis is placed on mafic dyke systems, magmatic provinces, and ophiolitic rocks to decipher the processes involved in oceanic crust formation and the genesis and tectonic evolution of ophiolites. We employ whole-rock major- and trace-element geochemistry, mineral chemistry, and in situ U–Pb zircon geochronology to constrain the timing, sources, and evolution of magmatic events. By integrating geochemical and geochronological data with tectonic and field-based observations, we aim to unravel crustal evolution, mantle–crust interaction, and magmatic processes. Our research also extends to the geological understanding and exploration of critical minerals, linking magmatic processes and geochemical signatures with the formation and enrichment of economically and strategically important mineral resources.
