Abstract : this paper, by analyzing the effect of differences of mineral structure of 2 1 layer minerals, the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation, reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges. the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals. the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity
文摘:分析2 1型礦物的結構差異、層間電荷性質以及在風化過程中某些性質的變化對層間陽離子吸引力的影響，對已有報道中一些矛盾的結果或不具普遍意義的結論進行了討論.得出幾個較為明確的結論：層間總電荷與四面體電荷所佔比例大小共同決定礦物對層間陽離子的固定能力；原生礦物中八面體結構與層間陽離子固定間的關系對次生礦物而言，也許並不一致；八面體中可變價陽離子的氧化還原，可導致礦物固定陽離子能力發生較大變化 -
