对新疆焉耆盆地沉积环境的研究发现，其侏罗系含煤系地层具有大量深水沉积特征，与传统浅水成煤的观点相悖。依据沉积地球化学的基本原理，选择渤海湾地区东营凹陷和西部吐哈盆地分别作为深水断陷湖盆和浅水聚煤盆地的标准模型，对焉耆盆地现有无机元素丰度资料作判别分析。结果表明，该盆地侏罗系地层元素特征与东营凹陷很相似，由此推知其古环境在更大程度上倾向于东部深水断陷湖盆。萨胡判别分析证明，与煤共生的粗碎屑岩不是形成于河流环境，而是形成于深水浊积沉积环境。这种观点的提出突破了浅水成煤的传统观念，为进一步研究该盆地特有的沉积、聚煤模式提供了一条新的思路，拓宽了煤岩及成煤环境研究的思维领域。
The study on the depositional environment of the Yanqi Basin in Xinjiang found that the Jurassic coal-bearing strata have a large number of deep-water sedimentary features that are contrary to the traditional viewpoint of shallow water coal formation. Based on the basic principles of sedimentary geochemistry, the Dongying sag in the Bohai Bay region and the Turpan-Hami basin in the west are chosen as the standard models of deep-water fault basin and shallow water coal basin, respectively, to discriminate the existing inorganic element abundance data in Yanqi Basin. The results show that the elemental characteristics of the Jurassic stratigraphy in this basin are similar to that of Dongying depression, suggesting that the paleoenvironment favors the eastern deep-water faulted lake basin to a greater extent. Sahu discriminant analysis proves that the coexisting coarse clastic rocks are not formed in the river environment, but formed in the sedimentary environment of deep water turbidite. This point of view has broken through the traditional concept of shallow water coal formation, which provides a new idea for further studying the unique sedimentary and coal-accumulating patterns in the basin and broadens the thinking field of coal and coal-forming environments.
