摘 要:硬铝石铝土矿的结构复杂,构造特殊,其成因与铝土矿的形成有关。本文在大量野外观察和显微镜研究的基础上,比较系统地分析了硬铝石铝土矿的各种结构要素和结构、构造特征及其成因,提出了我国最重要工业铝土矿的成因结构分类及迁移沉积模式。
Abstract: Diaspore bauxite is of complicated textures and special structures.No unanimous conclusion hasbeen drawn related to the formation of it.On the basis of the detailed field observation and the studyunder microscope,this paper has analysed systematically the origin and all kinds of textual andstructural elements of diaspore bauxite as well as the characteristics of textures and structures.Texture-genesis classification and migration-deposition model of our country′s important industrialbauxite have also been proposed in this paper.
