摘要
山东淄博铝土矿,是一水硬铝石型沉积铝土矿。它在本区有两个层位,一个是中石炭世的浅海和滨海相地层,另一个是早二叠世的陆相湖沼沼沉积地层。通过分析该区铝土矿地质特征,探讨了本区的铝土矿的成矿作用,认为该区铝土矿经过红土风化成壳、密度流搬运沉积、矿质定位成矿、后生蚀变改造和表生氧化富集等五个成矿阶段。
Zibo bauxite deposits in Shandong province are a sedimentary diaspores deposits. Ore beds are located in two horizons of middle Carboniferous shallow and littoral facies strata and early Permian continental lacustrine and swamp facies strata. Based on analysis of geological features, bauxite mineralization of the deposit is discussed. It is proposed that the Zibo bauxite deposits underwent five stages of mineralization like laterization, transportation and sedimentation of density fluid, location and mineralization of ore -forming elements, epigenetic alteration and shallow oxidization and enrichment.
