2:1矿物结构与阳离子固定及释放的关系

The effects of different structures of 2:1 layer minerals,layer charge location,and changes of structure and charge during the weathering process on the fixation and release of interlayer cations are reviewed.It could be concluded that the fixation capacity is determined by the total amount of interlayer charge originating from both octahedral and tetrahedral sheets.The realtionship between interlayer cation fixation and octahedral structure of the secondary minerals may be different from that of the primary mineralls.The oxidation and reduction of cations with varable valence can greatly influence the cation-fixation capacity.
