摘　　要：铧厂沟金矿床产于勉略缝合带中泥盆系三河口群郭镇岩组中.细碧岩是主要的含矿与容矿岩系.矿石类型为蚀变细碧岩型和石英脉型.主要的金属矿物为黄铁矿,金矿物是自然金.主控矿构造为寨子湾韧脆性剪切构造带.韧脆性剪切构造作用叠加导致岩石强烈变形、成矿物质活化和随热液迁移及在构造扩容地带沉淀是主要的成矿作用.Huachanggou gold deposit lies in Guozhen formation of Sanhekou group of Devonian of Mian-Luo suture zone. Its mineral-bearing series mainly consists of spilite. Its ore types include altered spilite and pyrite quartz-sericite altered and quartz vein. The main ore minerals are pyrite and nature-gold. The structure of major controlling ore is Zaiziwan brittle-ductile suture zone. The main mineralization includes superimposition of brittle-ductile tectonic action that leads to strong deformation and activities of metallogenic substance and motion with hydrothermal and deposition in tectonic expansion zone.
