The addition of Cl to the melt appears to have two prominent effects on iron in the melt: (1) dissolved Cl appears to perturb the magnetite-melt equilibrium, such …

Diffusion of F and Cl in dry rhyodacitic melt

WebIn this study, we have determined the combined effect of pressure and temperature on the compressional-wave velocity ( V P ) of Ne up to 53 GPa and 1100 K using Brillouin scattering in externally heated diamond-anvil cells. The phase transition from the supercritical fluid to solid phase was observed to cause a 10.5–11% jump in V P , and … WebNov 1, 2024 · The activation energies for F and Cl diffusion are quite similar in dry and hydrous (2.1–2.4 wt.% water) melts and were determined to be about 100 ± 10 and 155 … magnetita mineral caracteristicas
