Rocks and minerals preserve fundamental insights on igneous (volcanic and plutonic) processes and timescales. Variations in their textures and compositions are the results of magma crystallization, recharge and mixing during storage, mush formation and remobilization, pluton growth and maturation, magma ascent, degassing, shallow fluid-host rock interactions, and syn-eruptive processes during magma ascent. These processes operate on timescales of minutes to millennia, and unlocking the temporal information from rock and mineral textures provide complementary record of magmatic timescales. Innovations in methods and technologies in microanalyses, experimental tools, AI and machine learning approaches, and thermodynamical modelling advances our understanding of complex igneous and volcanic processes. This session offers a broad overview of novel developments and contributions using 'microscopic archives' drawing on insights from natural case studies, numerical models, and experimental works. We welcome contributions related to geochemical, experimental, and modelling studies of magmatic textures and compositions in igneous systems and their timescales.
