We report convection-free anorthite (cas 1302-54-1) dissolution experiments in a basaltic melt at 1280–1500 °C and 0.5 GPa on two different crystallographic surfaces, (121¯) and (3¯02) to investigate dissolution kinetics. The anisotropy of the anorthite dissolution rate along these two surfaces is negligible. Time series experiments at ∼1280 °C show that anorthite dissolution is mainly controlled by diffusion in the melt within experimental uncertainty. Analytical solutions were used to model the dissolution and diffusion processes, and to obtain the diffusivities and the saturation concentrations of the equilibrium-determining component (Al2O3) for anorthite dissolution into the basaltic melt. For the first time, we are able to show the physical and chemical characteristics of quench growth effect on the near-interface melt using high spatial resolution (0.3 μm) EDS analyses. For anorthite (An# ⩾ 90) saturation in a melt with 39–53 wt% SiO2 and ⩽0.4 wt% H2O, the concentration of Al2O3 in wt% depends on temperature as follows:lnCs,Al2O3=8.032(±0.192)-7882(±287)T,
