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 minerals 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 indicates that in the gold field, there are 3 tectonic stress stages, namely, the early style of S-N-trending compression, the middle stage of NW-trending compression and the last stage of NE-trending compression.
