The Jurassic sedimentary environment of Yanqi Basin has lots of deep-water sedimentary features in coal-bearing beds. 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。
Therefore, the Duolun basin is not an impact crater, instead its formation was related to the volcanic eruption during the late Jurassic Period. 因此，多伦盆地不是撞击形成，而与晚侏罗系上统火山喷发有关。
