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。

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 |
