山东莱州留村金矿床地质特征及找矿前景

Geological Characteristics and Prospecting Potentiality of Liucun Gold Deposit in Laizhou City of Shandong Province

摘要:

招远莱州成矿带是胶东最重要的金矿密集区，留村金矿床位于此成矿带南端，是发育于古老岩体间构造破碎带中的小型石英脉型金矿，矿体严格受NE向断裂的控制。近几年在该区开展地质勘查找矿工作，在其中深部发现了数个隐伏金矿体，通过对其地质、地球物理、地球化学特征、成矿时代等的分析，认为矿床中深部有较好的找矿潜力。

Abstract:

Zhaoyuan—Laizhou fault belt is the most important gold deposits concentrated area. Liucun gold deposit is in south part of this oreforming belt. It is a small and quartz vein type gold deposit developed in ancient metamorphic rocks. Ore bodies are controlled by structures with the trend of NE. According to geological surveying in this area and the study on characteristics of geology, geophysical and geochemical characteristics and oreforming age of the deposit, it is regarded that there is good potentiality for ore prospecting in deep part.
