本文在分析鉴定大量孢子花粉基础上,对吐鲁番盆地下侏罗统八道湾组、三工河组和中侏罗统西山窑组沉积环境和古气候以及孢粉与成煤关系做了尝试性探讨,划分出各段沉积时的气候变化,并且认为拟紫萁孢、拟苏铁粉、拟桫椤孢、石松孢等可以指示成煤环境。此外,本文对吐鲁番盆地早中侏罗世的最佳生油气候做了推断。 Based on the analysis and identification of a large number of spore pollen, this paper attempts to explore the relationship between sedimentary environment, paleoclimate, sporopollen and coal formation of Lower Jurassic Badaowan Formation, Sangonghe Formation and Middle Jurassic Xishanyao Formation, Turpan Basin , Divided into various sections of the deposition of climate change, and that the Pseudotaxis spores, mulberry florets, Pseudomonas splendens, stone pine spores can indicate coal environment. In addition, this paper made an extrapolation of the best oil-producing climate in the early Middle Jurassic in the Turpan Basin.
