Magmas potentially interact with surrounding rocks during their generation, ascent, storage, emplacement and eruption. Magma and wall-rock compositions, volatile content in melt, pressure, temperature and fO2, control the efficiency of the magma-rock interaction while the degree of equilibrium reached between magma and hosting minerals, influence the final rock texture. The timescale of the magma-rock or magma-mush interactions is of critical importance for understanding the magma differentiation processes (e.g., crystallization, assimilation, mixing, and volatile exsolution) and, consequently, the volcanic plumbing systems. We invite contributions that touch on the many aspects related to exchange/assimilation reactions between magma and deep crustal rocks, nucleation/growth and reabsorption of crystals, effects of crystallization kinetics on mineral chemistry as well as partitioning of trace elements between crystals and melts during interaction processes. We particularly encourage submissions on experimental petrology, thermodynamic and geochemical modelling, as well as on field studies.
