| 摘 要： | 偃龙煤田深部铝土矿矿床是豫西典型的隐伏铝土矿床，通过该沉积型矿产铝土矿、黏土矿、铁矾土、菱铁矿等诸矿产的含矿岩系特征认识，对该矿床的垂向上和纵向上的岩相相变特征和元素含量变化特征进行深入的分析和研究，元素含量变化与岩相相变关系密切，矿种之间存在相变过渡关系的特征.根据该认识，对沉积型铝土矿的诸矿种资源量估算方法提出了科学合理的认识.

| Abstract: | The Yanlong bauxite deposit is a typical concealed deposit in western Henan Province. The authors analyze the phase relationship and element contents of the orebodies of bauxite, clay, laterite and siderite in vertical and profile with ore-bearing characteristics. The variation in elements in ore has a close relationship with lithofacies. The relation between minerals is characterized by lithofacies transition. Based on this understanding, the paper offers a reasonable resources estimation for the sedimentary minerals. |
