| 9. | Moreover , hrtem observations indicate that the process is very selective : even in apparently homogenous illite or i / s , some crystals went opening and some remain unchanged . and the replacement of k cations by alkylammonium cations is not restricted to crystal edges , but extends to entire interlayer . the above facts are the basis of alkylammonium cations method applied to the diagenetic age of sedimentary rock
Iaa法是以沉积岩的粒度?年龄谱为基础的，利用这种方法可以获得同一样品不同粒级伊利石的年龄，随着粒级的减小，样品的年龄也减小，当碎屑伊利石的含量趋于零时，可以得到自生伊利石的成岩年龄；烷基胺阳离子取代法是一种化学方法，利用烷基胺阳离子的选择性替代性，可以去除碎屑伊利石成分中的k离子，从而能够获得自生伊利石的年龄。 |
| 10. | In this thesis , organic - montmorillorite ( org - mmt ) was obtained - by an ion - exchange reaction between na + - montmorillorite ( na + - mmt ) and alkyl ammonium bromide , leading to increase the basal spacing of montmorillonite . xrd analysis indicated that alkylammonium ions had already exchanged with na + ions in na - montmorillonite and long alkyl - chains had entered into the gallery of montmorillorite
X -射线衍射( xrd )分析结果表明有机胺阳离子已同蒙脱土中的钠阳离子发生离子交换作用，烷基长链进入蒙脱土层间，导致层间距扩大，并使蒙脱土层间亲水性转变成亲油性。 |
