Minerals are fundamental components of igneous (volcanic and plutonic) rocks. Variations in their textures and compositions are the results of magmatic and/or volcanic processes such as magma recharge and mixing, magma storage and crystallization, mush formation and remobilization, pluton growth and maturation, magma ascent, degassing, and syn-eruptive processes. These processes operate on timescales of minutes to millennia and unlocking the temporal information from various minerals provide complementary record of magmatic timescales. Minerals can also be used to reconstruct the original composition of the magma and its thermodynamic conditions, through modelling and experimental studies of elemental partitioning under magmatic conditions. This session offers a broad overview of these 'microscopic archives,' drawing on insights from natural case studies, numerical models, and experimental works. We welcome contributions related to volcanological, plutonic geochemical, experimental, and modelling studies of mineral textures and compositions with linkages to magmatic and volcanic processes and their timescales.
