| 摘 要： | 在对研究区191个泥质岩样品中Sr、Ba、Ga、Ru、B、K等微量元素含量测定的基础上,通过图解分析、统计分析等多种分析手段,找出它们与沉积环境之间的关系.并且在前人研究的基础之上,选定Sr/Ba,B、Ga、Rb三元素含量相对关系来判断鄂尔多斯盆地东部上古生界二叠系山西组的沉积环境.依据所获得的地球化学资料并结合地层古生物特征,证明了鄂尔多斯盆地山西组确有海相地层存在.

| Abstract: | In the paper, on the basis of mensurating content of trace elements such as Sr, Ba, Ga, Ru, B, K in the 191 shale samples in the studied area and through some methods such as graphic analysis, statistical analysis, we find out the relationship between these trace elements and the sedimentary environments. Based on the results of former researchers, we choose Sr/Ba and the relative relationship of B, Ga, Ru to identify sedimentary environment of the Permian Shanxi Formation in the eastern part of Ordos Basin. The integration of the obtained geochemical data, field geologic sections and laboratory observations of thin sections has proved the existence of marine stratum in Shanxi Formation of Ordos Basin. |
