Abstract Models concerning the diffusion of divalent cations (Ca2+, Mg2+, Fe2+, and Mn2+) in garnet have been subject to extensive research and application over several decades, yet discrepancies among available models persist. Particularly the diffusion rate of Mn2+, which is the fastest in garnet,...
