摘　　要：福建坂面-汤川位于中国东南沿海陆相火山岩地区,前人做的区域1:20万水系沉积物测量工作提出了尤溪-清溪远景区开展以寻找银、金铅锌矿为主的物化探工作和尤溪-朱溪远景区开展以寻找金银铅锌为主的物化探工作的建议。本文是在对区内开展地质调查研究基础上,在坂面幅和汤川幅开展1:5万水系沉积物测量,对区内元素分布规律及异常元素组合特征等进行研究,并结合异常区内地质特征,圈定了六个找矿远景区。Banmian tangchuan,Fujian Province,is located in the continental volcanic rock area along the southeast coast of China.The regional 1:200000 stream sediment survey work done by predecessors has proposed that the geophysical and geochemical prospecting work focusing on silver,gold,lead-zinc deposits should be carried out in Youxi Qingxi prospective area,and the geophysical and geochemical prospecting work mainly for gold,silver,lead and zinc in Youxi Zhuxi scenic area.Based on the geological investigation and research in this area,the 1:50000 stream sediment survey was carried out in Banmian and tangchuan sheets,and the distribution of elements and the characteristics of abnormal element combination in the area were studied.Combined with the geological characteristics of the abnormal area,six prospecting areas were delineated.
