Solubility of molybdenite in hydrous granitic melts at 800 degrees C, 100-200 MPa
Original language description
The solubility of molybdenite, MoS2, in fluid-saturated, subaluminous to peraluminous granitic melts was determined experimentally using rapid-quench cold-seal pressure vessels at 800 degrees C and 100-200 MPa, and analysis by laser-ablation ICP-MS. Molybdenite solubility seems to be independent of pressure, but it shows strong variations with oxygen and sulfur fugacity. At constant log fS(2) = -1.3 it increases from 0.1-0.7 ppm by weight Mo at the Co-CoO buffer to 29-38 ppm by weight Mo near the MnO-Mn3O4 buffer. The solubility isopleths are nearly parallel to the pyrrhotite-magnetite equilibrium, along which the solubility varies only slightly, from 10 ppmw Mo at the quartz-fayalite-magnetite buffer to 29-38 ppmw Mo at the MnO-Mn3O4 buffer. The observed solubility variations are consistent with the equilibrium MoS2(s) + 3/2O(2) = MoO3 (l) + S-2 and thus confirm that molybdenum(VI) oxide is the predominant species in subaluminous silicate melts at log fO(2) = -16 to -11.
