摘　　要：登封市白土坑铝土矿为沉积型铝土矿矿床，铝土矿产于奥陶系灰岩侵蚀面上，二叠系本溪组中段。矿体呈似层状、透镜状分布，厚度变化较大，较不稳定。通过矿区含矿岩系特征、矿体特征、矿石类型等分析研究，确定了寒武一奥陶系古侵斜面上的洼地和溶蚀坑是铝土矿富集的良好场所，本溪组是铝土矿的含矿层位，厚度大、比较连续且含矿较好等特点为其找矿标志。Dengfeng Baitukeng bauxite belongs to sedimentary deposits, and bauxite occurs in Ordovician limestone erosion surface and middle Benxi group. Ore body is stratiform in lenticular distribution, and its thickness changes large, relatively unstable. By analysis ore rock features, ore characteristic, ore type, etc., this paper determines the prospecting criteria, and provides a useful idea for the geological prospecting in this area.
