Interdiffusion coefficients of Al + Al vs. Mg + Si in the gehlenite–åkermanite system of melilite were determined by coupled annealing of synthesized end-member single crystals. The observed diffusion coefficients for a ...
Diffusion coefficients of cations, Ni, Co, Mn, Ca, Sr, and Ba, which are possibly in divalent state, and Fe in synthetic single crystals of gehlenite (Ca2Al2SiO7), which is one of the endmembers of melilite, were determined ...
The oxygen isotopic micro-distributions within and among minerals in a coarse-grained Ca, Al-rich inclusion (CAI), 7R-19-1 from the Allende meteorite, were measured by in situ using secondary ion mass spectrometry (SIMS). ...
