| 摘 要： | X射线技术在结晶矿物学上已得到广泛的应用,它测量精度较高,快速简便,对样品无破坏作用,是地质研究中的重要手段之一,它还广泛地用于大陆架地区的沉积物研究(俞旭等,1982; Devine,1972)。本文将对北部湾东北部x1钻孔近百米的沉积物岩芯全样进行X射线衍射定量分析研究,并根据矿物组合特征,探讨北部湾沉积区的沉积环境及演化过程。

| Abstract: | Mineral compositions of x1 core sediment samples from Beibu Gulf were studied by the X-ray diffraction method. The parameters Mc/Q, TF/Q and P/K revealed the sedimentary environment changes from Pliocene to Holocene, and showed that the studied area was shallow sea facies environment during Pliocene and Holocene, and that the land facies sediments were mainly distributed during Pleistocene, but that the transgression sequence was formed in the middle stage of Late Pleistocene. |
