| 摘 要： | 对小秦岭地区与金矿化有关的主要地质体中流体包裹体叠加组合标型特征和有关地质体Sr、H、O同位素组成的标型性研究证明，小秦岭地区中生代中温热液金矿化流体与中生代花岗岩浆分界出的热液之间没有直接联系，成矿流体更可能是一种演化的大气降水。花岗岩浆活动对金矿化的贡献主要表现为提供了一组局部热源，间接地影响了金矿化的形成。

RELATIONSHIP BETWEEN GOLD MINERALIZATION AND ACTIVITY OF GRANITIC MAGMA IN XIAOQINLING AREA: EVIDENCES FROM TYPOMORPHIC PECULIARITIES OF FLUIDS |
| |
| Abstract: | Relationship between Mesozoic granites and mesothermal gold mineralization in Xiaoqinling area has been studied by the typomorphic peculiarities of fluid inclusions and Sr, O and H isotopes of the main types of rocks. The study shows that the gold-bearing fluids of this area were not directly related to hydrothermal solutions from granitic magma, but to be an evolved meteoric water. The contribution of the Mesozoic granitic magma activities to the gold mineralization is to provide a series of local thermal sources and indirectly to influence the gold mineralization. |
