| 摘 要： | 峪耳崖金矿床位于华北板块北缘中段，是冀东地区金厂峪CD1]峪耳崖矿集区内赋存于花岗岩体及其与长城系围岩接触带内的大型金矿床。通过系统的成矿地质特征、流体包裹体、氢氧同位素、硫铅同位素和稀土-微量元素研究，结果表明：成矿温度为中高温热液环境，成矿流体为低盐度，成矿物质来源具有深源和幔源特征，金成矿作用过程具有排斥稀土元素的作用，Bi可作为富金矿体的指示元素。而峪耳崖金矿产于岩浆岩发育区和金厂峪金矿赋存于老变质岩区的表观成矿地质特征差异性、牛心山金矿“一墙之隔”的南北雷同性（南与金厂峪类同，北与峪耳崖类同）和它们成矿物质来源的同源性，则表明具体成矿就位地质环境的特定性决定了金矿床表观地质特征的特异性和复杂性。

| Abstract: | The Yuerya gold deposit is located in the middle segment of north margin of the North China plate. It is a large gold deposit in Jinchangyu-Yuerya mineralization concentration area and hosted in granite body and its contact zone with strata of the Changcheng system in the Eastern Hebei Province. Systematic investigations on geologic characteristics, fluid inclusions, oxygen and hydrogen isotopes, sulfur and lead isotopes, trace element and rare earth elements, show that the ore-forming fluid has the feature of low salinities and medium-high temperature; the metallogenic material was derived from deep-source and mantle substances. Because gold mineralization is not probable for rare earth elements, the Bi element can be regarded as indicator for high-grade ore. Compared with Yuerya, the Jinchangyu gold deposit is hosted in metamorphic rock in this area. The metallogenic geological characteristics of south part of Niuxinshan gold deposit are similar to that of Jinchangyu, while that of north part of Niuxinshan similar to that of Yuerya. However, those deposits have the same ore-forming material source. These characteristics suggest that the specificities of metallogenic geological setting determine the specialties and complexities of apparent geological characteristics of gold deposits. |
