摘　　要：冀东地区金矿产出较为集中,且地质特征有许多相似之处,通过对比研究金矿床的地质特征、矿体特征、围岩蚀变以及成矿条件,认为冀东地区金矿床成矿岩体应定位在燕山期花岗岩体,控矿构造定位于断裂或剪切带处。石英脉和黄铁矿脉可做为较好的直接找矿标志,此外,硅化。The gold output in Jidong district is relatively concentrated,there are many similarities about geological characteristics. The geological characteristics,ore body characteristics,wall rock alteration and minerogenetic condi-tion have been studied with comparative methods,and the prospecting direction of gold deposit has been analyzed. The bedrock of searching gold should concentrated on the yanshanian granite rock,ore-controlling structures for fault zone or shear zone. The quartz vein and pyrite vein can be taken as the sign for searching gold deposit. Besides,the alteration types,such as silicification,pyrite mineralization and so on,have an important effect on gold enrichment.
