| 摘 要： | 黄花山金矿系辽西建平地区重要的热液蚀变岩型金矿.新太古代变质基底片麻岩系为金矿的矿源层，中元古代侵入岩为金矿的主要容矿围岩，晚侏罗世侵入岩是金矿的成矿岩体.黄花山地区在印支期形成了北西向南东推覆的叠瓦状逆冲推覆构造，并长期活动，为成矿提供了空间.由于燕山期岩浆活动剧烈，即侵入体同下伏古老地层中金矿源层的重熔或捕获古老含金丰度高的层位，这些成矿热液沿黄花山叠瓦状逆冲推覆构造上升，并在逆冲推覆构造带中堆积形成了金矿体.通过总结、分析成矿的主要过程，建立了黄花山金矿的成矿模式.

| Abstract: | The Huanghuashan gold deposit is of important hydrothermal alteration rock type in Jianpng, Western Liaoning Province. The Neoarchean metamorphic basement of gneiss is the source bed for gold. The Mesoproterozoic intrusive rocks serve as the main host of gold ore. The Late Jurassic intrusive rocks are metallogenic rock bodies of the deposit. The imbricated thrust nappe structure from northwest to southeast was formed in Indosinian period in Huanghuanghua area, which provided space for the mineralization. Because of the intense Yanshanian magmatic activity, with which the intrusions remelted the underlying source bed or captured the high-Au strata, the ore-forming hydrothermal fluid run upward along the Huanghuashan imbricated thrust nappe structure and accumulated to form gold orebodies in the structural belt. With analysis of the ore-forming process, the metallogenic model of Huanghuashan gold deposit is set up. |
