摘要:

以Sr含量、Sr/Ba值和Th/U值等地球化学指标及生物遗迹化石作为判识标志,对鄂尔多斯盆地延长组长7油层组沉积环境水介质条件与古气候进行了分析:结果表明长7油层组沉积期古水介质Sr/Ba值为0.19~0.65、Th/U值为0.36~5.03,属陆相淡水环境;V/Ni值为1.75~5.53,属于还原环境;通过元素组合及生物遗迹化石、钴元素定量计算显示水体深度介于半深湖—深湖之间,最大古水深为50~120 m;孢粉组合分析古气候属较温暖潮湿气候。

关键词: 古盐度, 古水深, 古气候, 长7油层组, 鄂尔多斯盆地

Abstract:

Based on Sr concentration,the ratios of Sr/Br and Th/U,and biogliph fossil,we discuss the water condition and paleoclimate for the deposition of Chang7 oil layer in the Ordos basin.The results show that the ratio of Sr/Br and Th/U is from 0.19 to 0.65,and 0.36 to 5.03,respectively,indicating the water during the Chang7 Period was continental freshwater.The V/Ni ratio of 1.75-5.53 is fallen into the score of the reducing environment.The element assemblage,biogliph fossil,and Co quantitative match indicate that the water depth at the Chang7 Period was half-deep to deep lake,with the maximum depth of 50, 120m.The paleoclimate was confirmed as warm and humid climate by sporopollen assemblage.

Key words: Paleosalinity, Palaeo-depth;Paleoclimate, Chang-7 oil layer, Ordos basin.
