| 摘 要： | 对安徽张八岭构造带石英脉型金矿石英流体包裹体温度、成分和氢、氧同位素进行了研究，对成矿流体来源进行了探讨。研究表明，区内石英脉型金矿具有两类成矿流体，一类为中生代大气降水与经历水/岩交换的演化岩浆水的混合；另一类为中生代大气降水与原始岩浆水的混合。 |
| 关 键 词： | 流体包裹体 成矿流体来源 氢氧同位素 石英脉型金矿 张八岭构造带 |
STUDY ON THE ORIGIN OF ORE-FORMING FLUID OF QUARTZ-VEIN-TYPE GOLD DEPOSITS IN ZHANGBALING TECTONIC BELT,ANHUI |
|
| Abstract: | A study on the composition,temperature, δ 18O and δ D of the fluid inclusion of quartz－ vein－ type gold deposits in the Zhangbaling tectonic belt is carried out.Analysis of origin of ore－ forming fluid indicates that there are two types of fluid.One is that of mixing of Mesozoic meteoric water and evolutional magmatic water by water/rock interaction.The other is mixture of Mesozoic meteoric water and initial magmatic water. |
| Keywords: | Fluid inclusion origin of ore－ forming fluid oxygen and hydrogen isotope quartz－ vein－ type gold deposit Zhangbaling tectonic belt |
