| Mantle Fluids Involved in the Ore-forming Process of the Maoniuping REE Deposit,Sichuan:Evidence of C,H,O and S Isotopes |
| The two most important types of ores, i.e., barite pegmatite ores and carbonatite pegmatite ores, were chosen to analyze the carbon, hydrogen, oxygen and sulfur isotopic components of the ore-forming fluids.δ 13C V-PDB ratios are -3.0‰～-5.6‰, δD V-SMOW ratios are -57‰～-88‰,δ 18O H 2O-VSMOW ratios are 8.0‰～13.3‰,δ 34S V-CDT ratios are 3.3‰～5.9‰, and δ 13C V-PDB and δ 18O V-SMOW ratios of calcite are -6.9‰ and 7.3‰～7.4‰, respectively. The data obtained suggest that large quantities of mantle fluids were involved in the ore-forming process of the Maoniuping REE deposit. |
