江西宜春吴村金矿床赋存于吴村倒转背斜的南东翼。吴村金矿由三个含金矿化层位组成：即二叠系长兴组顶部、三叠系大冶组下部及两者之间的 F2破碎带。其中大冶组下部是主要矿化层位，为一套含碎屑的不纯碳酸盐类岩石。矿床成因为浅成低温热液型矿床。

Wucun gold deposit is located in the SE limb of the Wucun overturned anticline.The deposit con-sists of three gold-bearing layers,the upper part of Changxing Formation of Permian system,the lower part of Dayie Formation of Triassic system and the fractured zone (F2 )between them.The lower part of Dayie Formation is the major mineralization layer,which is predominantly composed of a suite of impure carbonate rocks with clast strata.The deposit genesis is considered as low temperature epithermal type.
