摘要
鄂西沉积铁矿含矿盆地为一断陷盆地,其周边被襄广、江南和武陵断裂所控制。盆内发育一套由泥盆系碎屑岩、泥质岩、碳酸盐岩组成的滨海相沉积,海侵和海退岩系构成了一个完整的沉积旋回。在含矿岩系中共有4层铁矿产出(Fe1-Fe4),Fe1矿层和Fe2矿层产于海侵体系域中,Fe3矿层、Fe4矿层产于高水位体系域中,其中以Fe3矿层规模最大,品位最高,是铁矿勘查的重点目标。
The West Hubei sedimentary basin bearing iron deposits is a fault - downcast basin, controlled by Xiang- guang, Jiangnan, Wuling faults. At the basin occurred Devonian sediments of littoral facies, consisting of clastic, clay and carbonate rocks. A complete sedimentary cycle were constituted by a transgressive and a regressive series. There were four iron ore beds （Fe1-Fe4） in the series, and Fe1 ,Fe2 placed at the transgressive systems tract （TST）, Fe3 ,Fe~ at the high- stand systems tract（HST）. The Fe3 bed were provided with great and high quality ores, so being main objective of pros-
