摘要

摘要: 滇黔北坳陷为南方海相地层的有利研究区域，发育多套海相页岩。上奥陶统五峰组与下志留统龙马溪组地层，尤其是五峰组—龙马溪组下段页岩作为优质烃源岩而备受重视。通过岩芯观察、薄片鉴定、X衍射分析及微量元素地球化学指标判识，对其进行页岩岩相划分与沉积环境分析。结果显示：滇黔北坳陷五峰组—龙马溪组下段地层共划分出六种页岩岩相：硅质页岩、黏土质页岩、钙质页岩、黏土质硅质混合页岩、黏土质钙质混合页岩、钙质硅质混合页岩，其中硅质页岩和黏土质页岩的TOC含量明显高于其余四种岩相。V/（V+Ni）、V/Cr、Ni/Co和U/Th指标指示五峰组—龙马溪组下段总体处于低能、滞留、局限条件，与深水陆棚环境匹配，Mo元素含量与四川盆地均值相当。五峰早期与龙马溪早期海侵的发生形成了以深水陆棚占主导的沉积格局，低能、滞留、局限的厌氧环境与快速海侵是有机质富集与保存的重要条件。

Abstract: Multiple sets of marine shales sediment in the Dianqianbei depression lead to a meaningful study area for marine stratum in southern China. The Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Formation, especially the Wufeng-Lower Longmaxi Formation considered as high-quality source rock has been raised much attention. We classified the shale lithofacies and analyzed the environment by cores observation, thin section identification, XRD and geochemical indicators of trace elements. Six types of shale lithofacies are classified, including siliceous shale, clayey shale, calcareous shale, clayey and siliceous shale, clayey and calcareous shale, calcareous and siliceous shale. Among the six types of shale lithofacies, TOC are richer in the siliceous shale and clayey shale than other four types. V/(V+Ni), V/Cr, Ni/Co and U/Th show Wufeng-Lower Longmaxi Formation sediments in the conditions of low energy, sluggish water flow and constrained sea water, which matches deep shelf. Mo content in Dianqianbei depression is near to the content in Sichuan Basin. Transgressions happen in early stage of Wufeng and Longmaxi, which lead deep shelf plays a vital role in the sedimentary environments. Anaerobic environment of low energy, sluggish water flow, constrained water condition and rapid transgression are essential in the richness and preservation of organic matter.
