三江北段查涌铜多金属矿床成矿流体特征——流体包裹体及氢氧同位素证据
Characteristics of ore-forming fluids from the Chayong copper-polymetallic deposit in the north of Sanjiang metallogenic belt:fluid inclusion and H-O isotope evidence
摘要
Abstract
Based on geological characteristics and mineralization stage division ore samples of the main hydrothermal ore-forming stage of the Chayong copper-polymetallic deposit in the north of Sanjiang metallogenic belt are collected to make the fluid inclusions microthermometry and hydrogen-oxygen isotopic analyses.The result shows that the inclusion is dominated by liquid phase,homogenization temperature 320 ～360 ℃ and salinities w(NaCl,eq)=35％ that is characteristic of magmatic hydrothermal deposit;δDvalues-110.0×10-3～-95.5×10 3 andδ(18Ov-sMow)=-2.2×10-3～2.5×10-3,average-104.4 × 10-3 and-0.6 × 10-3 indicating that fluid of the main ore-forming stage is dominated by magmatic water incorporated with a small amount of meteoric water.关键词
