摘　　要：对鄂西泥盆纪沉积铁矿中成矿元素Fe和主要伴生元素P、S、Ca、Mg、Si、Al的分布规律进行了研究,查明了这些元素在不同矿床和矿层,沿矿层的走向和倾向,由地表至地下含量的变化,揭示了影响各类元素含量的古地理、沉积相、氧化还原及生物化学条件,这对在该区寻找富矿、低磷矿和自熔性矿将有所启示。Distribution law of ore-forming element Fe and major associated elements P, S, Ca, Mg, 5i, AI in the Devoman sedimentary iron deposits of western Hubei were investigated in different deposits and beds, along strike and dip, from that various elements contents are controlled by biochemistry effect, guiding the prospecting for o The paper determines the feature of the elements contents surface to subsurface in same ore bed. The study results reveal palaeogeography, sedimentary facies, condition of oxidation-reduction and rich, low phosphorus, and self-melted ores in this area.
