福建德化淳湖金矿地质特征及找矿标志

摘要

Chunhu gold ore exist in fourth acidic valcanoclastic rocks of Upper Jurassic Nanyuan Formation and are controlled by secondary faults of Jikeng-chunhu NW fault. The four gold orebodys have been discovered in the deposit now and its act like a lenticular and long lenticular occurrence. The ore types are the pyritization guartz vein and sericite- pyritization-silicifield alteration rock. Preliminary studies show that the gold deposit belongs to the structural altered rock type which relating the late Jurassic volcano effect.%德化淳湖金矿产于侏罗系上统南园组第四段酸性火山碎屑岩中，主要受祭坑-淳湖北西向断裂的次级断裂控制。目前已发现4条金矿体。矿体呈长透镜状产出，矿石主要为黄铁矿化石英脉型、绢云母化黄铁（褐铁）矿化硅化蚀变岩型。初步研究表明该金矿为与晚侏罗世火山作用有关的构造蚀变岩型金矿。
