摘　　要：通过对安徽庐江龙桥铁矿ZK1004孔(深617m)132个古地磁标本的研究,认为该矿区赋矿地层的时代应属晚侏罗世(136～147Ma);其上覆火山岩地层应归属下白垩统;将龙门院组、砖桥组划归下白垩统较为合理.In this paper, the 132 rock specimens of ZK1004 borehole of Longqiao iron ore mine in Lujiang, Anhui Province, are used for paleomagnetism. The measurement results of the specimens show that the age of the iron bed should belong to the Late Jurassic (136 - 147 Ma), the volcanic rocks covering the iron bed to the Early Cretaceous, and the Longmenyuan Formation and Zhuanqiao Formation to the Late Cretaceous.
