| 摘 要： | 本文对取自安徽嘉山坡缕石矿床不同层位的坡缕石粘土所做的红外光谱和Ｘ射线衍射分析表明：不同层位粘土的结构类型不同，坡缕石含量高的层位其结晶程度低；坡缕石含量低的层位其结晶程度高，为斜方晶系。文中对坡缕石的形成机理和造成结晶程度差异的原因进行了分析。

| Abstract: | The palygorskite clays from different beds of Jiashan palgorskite deposit,Anhui province,were studied by IR and XRD.It is found that there are differences in the structural characteristics of clays in different beds.In the bed with higher content of palygorskite,the palygorskite has lower crystallinity which displays clinorhombic system.In the bed with lower content of palygorskite,the palygorskite has higher crystallinity which displays orthorhombic system.The forming mechanism of palygorskite and the cause of cystallinity differences are discussed in this paper. |
