| 摘要 | Solubility experiments of Mn-columbite (MnNb2O6) and Mn-tantalite (MnTa2O6) were conducted under water-saturated conditions in synthetic haplogranitic melts containing different amounts of phosphorus at 800 C and 100 MPa. All experiments were carried out in cold-seal rapid quenching pressure vessels (RQV) with water as a pressure medium. Experimental results show that: (1) the solubilities of MnNb2O6 and MnTa2O6 in peralkaline melts are higher than those in peraluminous melts; (2) phosphorus has strong influence on the solubilities of MnTa2O6 and MnNb2O6 in peralkaline melts, Kisli!' and Kg decrease from 104.89 x 10(-4) mol(2)/kg(2) and 107.62 x 10(-4) mol(2)/kg(2) for melts without P2O5 to 16.11 x 10(-4) mol(2)/kg(2) and 7.96 x 10(-4) mol(2)/kg(2) for melts containing 4.00 wt% P2O5, respectively; (3) phosphorus has less influence on the solubilities of MnTa2O6 and MnNb2O6 in peraluminous melt, Kig' decrease from 4.50 x 10-4 mol(2)/kg(2) for melts without P2O5 to 0.73 x 10(-4) mol(2)/kg(2), and Kg from 3.57 x 10(-4) mol(2)/kg(2) to 0.14 x 10(-4) mol(2)/kg(2) for melts contaning 5.00 wt% P2O5. Taking the structural role of phosphorus into account, P decreases the solubility of Mn-columbite and Mn-tantalite via competing for network modifiers. |
