永吉头道川金矿床典型矿床研究

Study of Toudaochuan gold deposit,Yongji,Jilin Province

永吉头道川金矿床规模较小,但它代表了吉中地区晚古生代火山作用金矿的成矿事件。本文从地质构造环境及成矿条件、矿体特征、矿石物质成分、围岩蚀变、成矿阶段、成矿时代、地球化学特征、成矿物理化学条件加以归纳整理,进而总结矿床的控矿因素,矿床就位机制。

Toudaochuan gold mine of Yongji represents the guitar in the Late Paleozoic volcanic gold mineralization events,though deposit scale is small.In this paper,environmental and geological conditions of ores,ore characteristics,the ore material composition,wall-rock alteration,mineralization stages,mineralization age,geochemistry,physical and chemical conditions for mineralization to collate,and then summed up deposit ore-controlling factors and deposits in place mechanisms.
