| 摘 要： | 在松辽盆地白垩系含油地层中,首次发现了火山角砾岩沉积体,其粘土胶结物由单一的绿泥间蛭石组成。本文报道了对该矿物的X射线衍射、红外光谱、扫描电镜、化学组成及阳离子交换量的分析结果。分析了它的形成机制和具体条件,认为它是在成岩过程中,在富Mg和富Fe的条件下,由蒙脱石转化而来。

| Abstract: | Sedimentary volcanic breccia, cemented by clay material composed exclusively of mixed chlorite-vermiculite, was discovered in Cretaceous oil-bearing strata, Songliao Basin. X-ray diffraction data, infrared spectra, scanning electron microscope analysis, chemical composition and cation exchange properties are reported in this paper for the mixed chlorite-vermiculite: It is considered that the mineral may have been formed by the alteration of montmorillonite in a Mg-, Fe-rich environment during diagenesis. |
