黔中—川南石炭纪铝土矿的地球化学特征

Geochemical characteristics of Carboniferous bauxite deposits in central Guizhou southern Sichuan

论述了黔中—川南铝土矿成矿带内早石炭世和晚石炭世铝土矿及其下伏地层的主要化学成分、稀散元素、稀土元素的地球化学特征，进而探讨了铝土矿的成矿母岩———下寒武统、下奥陶统和下志留统的泥、页岩及碳酸盐岩的成矿意义。

This paper discusses the main chemical compositions and dispersed element and REE geochemistry of Early and Late Carboniferous bauxite deposits and their underlying strata in the central Guizhou southern Sichuan bauxite metallogenic belt and the host rocks of bauxite Lower Cambrian, Lower Ordovician and Lower Silurian mudstone shale and subordinate carbonates.
