| 摘 要： | 本文主要讨论了柴达木盆地第三系粘土矿物的穆斯堡尔效应，分析了有关粘土矿物的响应特征及铁离子的赋存状态，测定了Fe2+/Fe3+值，并依据该比值对研究区的沉积环境和沉积相作了判别。表明含油气盆地中粘土矿物的铁穆斯堡尔效应不但可用来鉴别含铁的粘土矿物类型，而且在沉积环境和沉积相的判别中具有重要的应用价值。

| Abstract: | In this work the Mossbauer effect of clay minerals in Tertiary System of Qaidam Basin is discussed and the state of Fe2+ and Fe3+ in some clay minerals is also analy zed. The ratios o f Fe2+/Fe3+ in different samples are measured. According to the ratio of Fe2+/Fe3+, some sedimentary environment and facies sequence in some sections of the basin are divided. This indicates that not only the type of clay minerals containing Fe, but also sedimentary environments a nd facies sequences may be divided by Mossbauer effect of clay minerals in oil basin. |
