福建省尤溪峰岩铅锌银资源潜力及找矿方向探讨

Potentials of lead,zinc and silver resources and their prospecting direction at Fengyan,Youxi ,Fujian

福建尤溪峰岩铅锌银矿床产于龙北溪组(Pt2-3l)绿片岩中,成矿构造环境为大陆古裂谷,矿床成因类型属块状硫化物矿床。通过一年多的资源调查评价(地质大调查项目)工作,地质找矿取得了重大进展,已控制的铅锌银资源量均达大型规模,预测该区具有寻找超大型矿床的潜力。该矿床的解剖对于福建北部、西部及相邻的浙江南部寻找同类型矿床具有指导意义。

The Fengyan lead-zinc-silver deposit,Youxi,Fujian,occurs in greenschist of the Longbeixi Formation(Pt 2-3 l).Its metallogenic-tectonic environment was the continental paleo-rift.It is genetically of massive sulfide type.Through more than one year of resources inves-tigation and evaluation(large-scale geological survey project),major advances have been made in geological and mineral prospecting work and the controlled lead-zinc-silver re sources have reached a large magnitude.It is predicted that this ore district has the poten tial for finding a super-large ore deposit.The analysis of this deposit has great guiding sig nificance for looking for deposits of the same type in northern and western Fujian and neigh boring southern Zhejiang.
