Cation diffusion in aluminosilicate garnets: experimental determination in pyrope-almandine diffusion couples

Diffusion couples made from homogeneous gem quality natural pyrope and almandine garnets were annealed within graphite capsules under anhydrous conditions at 22-40 kbar, 1057-1400 degC in a piston-cylinder apparatus. The concentration profiles that developed in each couple were modeled to retrieve t...
