摘要
通过对合肥铝土矿带内具有代表性的后槽矿床的铝土矿,以及对下伏奥陶系页岩,奥陶系和寒武系白云岩的研究,从铝土矿的富集率,稀散元素组成特征和稀土元素分布模式特征等几个方面,论述了后槽铝土矿的成矿母岩,主要是下奥陶统的页岩。
On the basis of researches on the typical Houcao bauxite deposits in Zunyi bauxite belts, the underlying Ordovician shale and dolomite, and the Cambrian dolomite, this paper deals with the ore-forming mother rocks of Houcao bauxite deposits, mainly the lower Ordovician shale, from the aspects of enrichment ratio of bauxite deposits, forming features of rare elements and distribution model features of rare elements.
