建瓯奖坑金矿（化）体呈似层状、脉状、透镜状产于早元古代大金山组变质岩推覆于中生代早侏罗世梨山组的缓倾角断裂带上及大金山组变质岩内陡倾角断裂中。成矿物质来源于变质岩，成矿热液有变质热液和推覆运动热液，金矿主要成因类型为混合岩化变质热液改造型金矿床。

The Jiangken Au deposit is situated at the junction of the zhenghe-Dapu NE-trend fault zone and the Ninhua-Nanping NEE-trend fault zone, which is located at border on SongxiJiangxi depression and Pucheng-Yangyuan uplift. Au orebodies are found in fault belt of nappe structure and steep fault in metamorphic rock. Au-Ore is derived form metamorphic rock and magmatic rock. The main genetic types of deposit belong to the migmatization metamorphic-hydrothermal Au deposit.
