摘要
Ⅱ1金矿体赋存于上元古界澜沧江群惠民组上段断层破碎带中,微粒金为主,硅化蚀变。强烈风化形成较深氧化带,属火山喷发期后中低温热液—表层强氧化型金矿。
The Au ore body Ⅱ1 exists in the fault fracture zone of Upper Proterozoic Lancangjiang Group Huimin Formation Upper Member.The main ore is formed by the micrograined Au.The rather deep oxidation zone is formed by the silisification and intense weathering process.It belongs to the Au deposit of middle-low T hydrothermal—surface intense oxidation type after volcanic eruption period.
