| 摘 要 为探究二连盆地川井坳陷白垩系地层元素地球化学特性及其地质意义，借助C3钻孔选取二连组到腾格尔组的20个白垩系地层样品进行研究，通过X射线荧光光谱(XRF)和电感耦合等离子体质谱(ICP-MS)方法分析了样品的元素地球化学特征，据此探讨了其对源岩属性，构造背景及古沉积环境重建的意义，并通过元素垂向特征演化图的高度耦合性，证明了气候干湿变化与古盐度及氧化还原之间密不可分的关系。 |

| In order to explore the element geochemical characteristics and geological significance of Cretaceous strata in Chuanjing depression of Erlian Basin, 20 Cretaceous strata samples from Erlian formation to Tengger formation were selected by C3 borehole for study. The element geochemical characteristics of the samples were analyzed by XRF and ICP-MS, and their source rock properties and structural back were discussed The significance of reconstruction of landscape and paleosedimentary environment, and through the highly coupling of the evolution map of the vertical characteristics of elements, proved the inextricable relationship between the climate dry and wet changes and paleosalinity and oxidation-reduction. |
