摘要
贵州铝土铁质岩系的下伏基底有碳酸盐岩及陆源碎屑岩,是它们经过长时期风化剥蚀作用,在早碳世海浸初期由各种复杂的沉积作用,在特殊的水体中聚集成含铝土铁质岩系,包括了铝土矿,铁矿,耐火粘土及其它稀有金属矿产。与特殊的古地貌及古地理环境关系密切.
In terms of analysis of evolution features of paleogeography of Early Paleozoic in Guizhou, the author suggests that the material resources be mainly from the dolomite top of Lousanguan formation of Late Cambrian period and from the sedimentary products caused by long -time weathering ero-sion of Tongzi formation of Early-Middle Ordovician epoch, Honghuayuan formation, Meitan formation , Shizipu formation and Baota formation.
According to the researches made by predecessors, the author considers that the bauxite rock system was approximately formed in two facies belts, that is, the shore lagoon depression facies belt and the inland lagoon depression facies belt.
