| 中文摘要: |
| 老旧矿山建矿时间长,经过资源的大规模开采,后备资源严重不足,亟需寻找接替资源,延长矿山服务年限。研究其成矿规律,为后备资源勘查指明方向,对老旧矿山具有重要指导意义,而灵湖金矿床就是众多老旧矿山、甚至危机矿山中很有代表性的一个。灵湖金矿床位于华熊台缘坳陷小秦岭隆起金、钼多金属成矿带,构造基底为太古宙太华岩群组成的变质核杂岩,区内矿体主要受东西向断裂控制,由含金石英脉及其底部的蚀变岩组成,厚大富金矿体走向上分布于断裂构造转折端的近东西向和南东东向部位,倾向上分布于产状由陡变缓的过渡部位。本文通过对成矿地质背景、矿区地质特征等方面的研究,对其矿化富集规律及找矿标志进行系统分析、归纳和总结,指明找矿方向,研究成果对该区周边众多矿山扩储增量提供了借鉴。 |
| 英文摘要: |
| Linghu gold deposit is located in Xiaoqinling uplift gold and molybdenum polymetallic metallogenic belt of Huaxiong platform margin depression. The tectonic basement is metamorphic core complex composed of Archean Taihua Group strata. The ore bodies in the area are mainly controlled by EW trending faults, which are composed of gold bearing quartz veins and altered rocks at the bottom. The thick and large gold rich ore bodies are distributed near EW and SEE trending parts at the turning of fault structure. Through the study of metallogenic geological background and geological characteristics of the mining area, this paper systematically analyzes, comcludes and summarizes the mineralization enrichment law and prospecting indicators, and points out the prospecting direction, which has important guiding significance for the expansion and accumulation of many ore hills around the area. |
