| 中文摘要: |
| 黄花山金矿处于华北地台北缘燕山台褶带(燕山沉降带)过渡带的马兰峪变质核杂岩南部,该区成矿地质条件有利,矿床成因复杂。文章分别从成矿地质条件、成矿流体、成矿时代及成矿温度等方面进行分析,认为太古宙变质岩是区内金矿的主要矿源层,中、新元古界碳酸盐岩为赋矿地层；成矿过程中水的来源是以岩浆水为主,且在后期混有一定量大气水的多来源混合水；矿石中的S来源于一系列酸性、中酸性的脉岩侵入；成矿年龄晚于燕山晚期；成矿温度为中低温。总结认为该矿床的矿床类型为受拆离滑脱构造和燕山晚期岩浆活动控制的石英脉型金矿。 |

| The Huanghuashan gold deposit is located in the southern part of the Malanyu metamorphic core complex, the transition zone of Yanshan fold belt (Yanshan subsiding belt) which belongs to the northern margin of north china platform. There are favorable geological conditions for gold mineralization and the deposit genesis is complicated. This paper discussed the deposit from aspects of metallogenic geological conditions, ore-forming fluid characteristics, mineralization epoches, and metallogenic temperature. In conclusion, the Achaean metamorphic rocks is the main source bed for the formation of the Huanghuashan gold deposit, and the Middle-Late Proterozoic carbonate rocks are the main ore-bearing layers. The ore-forming water is a mixed water dominated by the magmatic water and mixed by the meteoric water in the late evolution stage. The sulfur in the ore is sourced from a series of felsic and intermediate - felsic dykes. The metallogenic age of the deposit is later than the Late-Yanshanian period. The mineralization temperature is low and intermediate temperature. In summary, the Huanghuashan gold deposit is a quartz vein type deposit which was ontrolled by the decollement structure and Late-Yanshanian stage magmatic activity. |
