| 摘 要： | 通过对黔北铝土矿含矿岩系下伏灰岩中丰富的筵类化石和含矿岩系中大量的植物化石的鉴定和研究。结合对黔北地区沉积旋回和古气候的分析，认为黔北铝土矿含矿岩系的下伏灰岩为黄龙组地层。而上覆于黄龙组之上的铝土岩系，其沉积时代应为早二叠世马平组沉积期的晚期，层位相当于Pseudoschwagerina化石带。

| Abstract: | Through examination and study of plentiful Fusulinacea fossils in the limestone underlying the bauxite-hosted rock series and a great deal of phytolite in the bauxite-hosted rock series in northem Guizhou, in combination with the analysis of sedimentation cycle and palaeoclimate there, the authors think that the underlying limestone belongs to the Huanglong Formation strata, while the bauxite-hosted rock series overlying tile Huanglong Formation yielded a sedimentation age corresponding to Early Permian, i.e., the late stage of the Maping Formation, corresponding to the fossil bed of Pseudoschwagerina. |
