| 摘 要： | 我国球粘土应成为独立矿种，湖沼球粘土中含“内胶体”的自生高岭石是生物有机质作用造成，水云母、I-M间层粘土矿物及有机质会增加可塑性、粘结性及干燥强度，钾、钠的增加可降低烧结温度。沉积球粘土与残积成因高岭石为无序或较无序，古生代煤系高岭石为有序和高度有序，岩浆热液成因的高岭石常为有序或高度有序；北方古生代软质粘土（紫矸）为规模较大、较为均匀稳定的高度有序高岭石，应积极开发。硬水铝石岩溶铝土矿应属于生物有机质成矿作用的沉积型铝土矿。

| Abstract: | Ball clay should be defined as an independent ore in China.The autonomous kaolinite containing endo-colloid in ball clay is formed in lake basin log under influence of biogenetic organic matter.Hydro-mica,I-M interlayer clay minerals and organic matter lead to plasticity,coherence and drying strength increment and lower K,Na to decrement of the sintering temperature.The sedimentary ball clay and the residual kaolinite are disordered or relatively disordered kaoloinite,kaolinite in Palaeozoic coal measures ordered or highly ordered,magmatic hydrothermal kaolinite ordered or highly ordered.Palaeozoic soft clay(purple gangue) in the coal measures occurs as relative uniform,stable and large size highly ordered kaolinite deposits that should be vigorously developed.Karst diaspore bauxite should be bio-organically sedimentary bauxite deposit. |
