| 摘 要： | 峪耳崖金矿是冀东地区一个典型的热液型矿床、硫、铅同位素组成表明太古宙变质岩是本区金矿的主要矿源层，是壳幔相互作用的结果，氧同位素表明水的来源以大气降不为主，在大气降水深循环过程中，金从围岩中多次萃取，频敏的岩交活动使成矿元素进一步富集，成矿流体的组成、盐度、ＰＨ，Ｅｈ，ｆ（Ｏ２）表明金是以「Ａｕ（ＨＳ）２」络离子形式迁移，由于物理化学条件的改变，导致了金的沉淀，在ＮＥ和ＮＮＥ向构造裂隙发育部位形成

| Abstract: | Yuerya gold deposit is a typical post magmatic hydrothermal deposit in the eastern Hebei Province. Its sulphur isotopes have a characteristic of the upper mantle. Sulphur and lead isotopes show that the granite and gold deposit could have come from the same source of region lower crust. Oxygen isotopes indicate that water is mainly from atmospheric water. Composition, salinity, pH, Eh and f (O 2) of the ore forming fluids reflect the gold migration with Au(HS) 2] -. The change of condition of physical chemistry resulted in precipitation of gold. |
