| 摘 要： | 莲花山斑岩型Ｗ－Ａｕ矿床矿化脉的流体包裹体氢氧同位素特征表明，成矿流体来自岩浆水与大气水的混合水，从早到晚，岩浆水成分减少，大气水成分增加。成矿流体的氧同位素、流体包裹体的盐度和成矿温度表明，较早的黑钨矿一石英脉形成于岩浆热能及热液向上推进的过程中，而后的白钨矿－硫化物－石英脉和碳酸盐－石英脉形成于岩浆热能及热液向下退缩的过程中。

| Abstract: | Hydrogen and oxygen isotope, salinity, and homogenlzation temperature of fluid inclusions show that ore fluid in Lianhuashan porphyry-type W-An deposit evolves from early magmatic water to late meteoric water. Wolframite-quartz vein and scheelitosulfide-quartz vein are formed in the process of magmatic energy and hydrothermal fluid ingressing upward and retreating downward respectively; Carbonate-quartz vein is formed mainly by heated circulation meteoric water. |

| Keywords: | porphyry-type W-An deposit ore fluid hydrogren and oxygen isotope |
