Experimental phase-equilibrium Al- and Ti-contents calcic amphibole MORB--A semiquantitative thermobarometer
2012/4/1
Calcic amphiboles were synthesized from a natural mid-ocean ridge basalt (MORB) in 39 experiments representing 24 sets of pressure-temperature ( P -T ) conditions ranging from 650?50 8C, 0.8?.2 GPa, a...
