| 摘 要： | 海沟金矿是大型石英脉型金矿床,矿体严格受NE向断裂构造控制,成矿时代为晚侏罗世-早白垩世.矿石中金属矿物以黄铁矿、自然金、方铅矿和黄铜矿为主.28号主矿脉中,Au平均品位20.59×10-6.成矿物质来自地层和岩体.对构造应力场研究表明,矿区有3期构造应力场,分别是早期近S-N向挤压、中期NW向挤压和晚期NE向挤压.成矿期应力场最大主压应力方向为NE向.

| Abstract: | Haigou gold deposit in Jilin province is of a large quartz vein type. The ore bodies are strictly controlled by NE-trending fault structures.The ore-forming period ranges from Late Jurassic to Early Cretaceous.The metal mineral s in ore are mainly pyrite,native gold,chalcopyrite and galena.The average grade of gold in the main ore vein is 20.59 ×10-6.Tectonic stress field analysis in dicates that in the gold field,there are 3 tectonic stress stages,namely,the ear ly style of S-N-trending compression,the middle stage of NW-trending compress ion and the last stage of NE-trending compression. |
