福建尤溪肖坂金矿金矿体主要受韧性剪切带控制，呈层状、似层状，贮存于中一晚元古代大岭组变质岩中，为典型的绿岩带韧性剪切型金矿床。通过对该矿区矿石的矿相学观察、扫描电镜下的能谱分析以及电子探针的分析，发现该区金的存在主要有两种形式，即以包体金形式包裹于黄铁矿、黄铜矿、石英和闪锌矿中和以粒问金形式分布于黄铁矿、石英等矿物的粒间。Ag与Au出现类质同象，Ag含量最高可达到6．91％，分析结果表明还含有少量的Fe存在。

The Xiaoban gold deposit is controlled by the tenacity and brittle shear zone, distributed over the in layers or quasi-layers and belongs to the one of ductile shear zone type of a gold deposit in the green stone belt. By miner graphical, the energy dispersive spectroscopic anal- ysis and electron probe analysis, it is found that there are two kinds of forms for the gold in this area. one is native gold mineral, and the other is mechanical mixture, which exists be- tween solid solution and adsorbed matter in auriferous minerals （pyrite, chalcopyrite, quartz, calcite and galena） . Some Ag isomorphic substitute the Au, whose maximum content could be 6.91%. Some＇ Fe content was detected, too.
