本区铝土矿中的含水氧化铝矿物主要是一水硬铝石,一水软铝石和三水铝石只在少量样品中发现,这说明本区铝土矿物生成的物理化学环境基本是一致的。因此铝土矿的结构类型对该区铝土矿的成因揭示就更加重要。近年来本区铝土矿从成份分类逐渐衍变为成份加结构分类,有向结构—成因分类的趋势,看来对本区铝土矿拟订出一个结构 The hydrous alumina minerals in this area bauxite are mainly diaspore, boehmite and gibbsite only found in a small amount of samples, indicating that the physical and chemical environment of bauxite formation in this area is basically Consistent. Therefore, the type of bauxite structure reveals the genesis of bauxite in this area is even more important. In recent years, the bauxite in this area has gradually evolved from the classification of ingredients into a trend of composition-plus-structure classification and directional structure-genesis classification. It seems that a structure for the bauxite in this area has been drawn up
