Short summary
Volatile diffusivities in silicate melts control the nucleation and growth of bubbles in ascending magma. We investigated the diffusion of CO2 in an anhydrous and hydrous leucititic melt at high temperatures and high pressure. CO2 diffusion profiles were measured via attenuated total reflection Fourier transform infrared spectroscopy. CO2 diffusion increases with increasing temperature and water content. The data can be used to understand the CO2 degassing behaviour of leucititic melts.
