Characteristics of ore-forming fluids in Dafulou tin-polymetallic ore deposit, Guangxi, China
摘要
Abstract
Based on the study of the fluid inclusion and microthermometry, the characteristics and evolution of the ore-forming fluid of the Dafulou tin-polymetallic deposit were studied. The results show that there are six types of fluid inclusion: I , single-phase gas inclusions; II, single-phase brine inclusions; III, two-phase vapor-rich inclusions; IV, two-phase liquid-rich inclusions; V, carbon dioxide-bearing inclusions; VI, containing NaCl daughter minerals inclusions. The homogenization temperature ranges from 120 to 430 ℃, but the main temperature scope ranges from 120 to 145 ℃ and 380 ℃ to 430 ℃. The salinity ranges from 17.00% to 22.00%, characterized by the high salinity and magmatic-hydrothermal fluid. And, the fluid, whose density ranges from 0.158 to 1.105 g/cm3 formed under the medium-high pressure of 12.0-65.0 MPa. The characteristics of the ore-forming fluid for the Dafulou tin-polymetallic deposit accords with the other ore deposits in the Dachang ore field, which may suggest the same source and evolution.关键词
