Jinchanggou gold deposit is one of the most valuable mineral (bed) points in the Qingmuchuan- Cangshe gold metallogenic belt, the deposit preserves in Qingmuchuan-Guankouya ductile shear zone of Pt2-3bk23-1, and has good geological conditions and huge prospecting potential. Through the analysis of the geological characteristics of the deposit and ore, the ore bearing rock series and the chemical composition of surrounding rock, trace elements, rare earth elements, fluid inclusions and sulfur isotopes, it was suggested that the ore bodies are controlled by ductile shear zone and mineralization is closely related to the magnetite quartzition, pyritization, etc. wall rock alteration. Pyrite is the gold carrying minerals and its sulfur extracts from Bikou Group source rocks in the process of fluid rock. The enrichment of gold element may pass through multiple stages. Diagenesis and mineralization has a different period. |
